Perfect Blue

They are both psychological and thriller anime. Both made on the same year too so you'd get the same feeling while watching one or the other. The only difference is that Serial Experiments Lain is more of a sci-fi series and the Perfect Blue movie is about an idol. Both have the same element where the characters cannot distinguish reality from fantasy/other world.  

They give the same surreal and creepy feeling. 

They both have a thin line between what is real and what is fake, where the protagonist begins to wonder just who they are. If you like shows where you can't tell the difference between what's real and what is just a dream or a trippy sequence that was put in for symbolism, these are the shows for you.  

Similar in the dementia/psychological content and are good if you want to be in a vegative state after watching both of these. In my opinion, they also have a slight thriller feel to them. 

They have the same concept of existence the second world (or personality) which is connected with our one. Perfect blue touches more individual case when Lain is focused on society. 

- Both are psychological and dementia. - We have a girl , living a normal life , until he sees things that are hard to believe , playing with his mind , he doubted its existence. Until finally he realizes reality. 

Both present a fractured reality and protagonists whose personal conflicts are deeply rooted in the psychological. They share a creepy/ depressing atmosphere and relatively slow build-up.  

both characters going through an identity crisis, both psychological suspense ambos personagens passando por uma crise de identidade,ambaos suspense psicologico 

Psychologically driven titles that focus on the main character's perspective as the line between reality and illusion disappears, leaving them to unravel a bizarre web of truths and deceptions. Both anime feature non-standard methods of storytelling so that the viewer is left guessing along with the protagonists, though enough is stated by the end for a conclusive ending to be reached. They were also both made in 1998 and take place during "the present", thus they both have a clear 90's stylization. It should be noted that Serial Experiments Lain is more slowly paced than Perfect Blue (especially as the later is an 80 minute movie versus a 12 episode TV series). Despite this their general plot progression is similar in many ways. In this way they often "feel" similar at many points. read more 

In both anime, the protagonist is exploring another side of themselves. Both are pretty trippy psychological and slightly horror anime. The visuals are also pretty similar. 

If you're interested in stories that deal with themes of identity and technology, you might like these anime. Both use non-traditional methods of storytelling (though Serial Experiments Lain definitely takes that to the extreme) and both of them contain elements of horror. 

The break down of the psyche is a painful for those watching it happen. Just like in Serial Experiments Lain, we see the main character of perfect blue slowly descend. The art styles of this show are very similar with its vivid coloring and ghoulish faces in certain scenes. I found myself wondering if the show was either directed by the same person, or done by the same studio. Both of pieces take a bit of deeper look to fully understand and leaves the audience with a lot of inexplicit story telling.  

Both works have a dark, unsettling tone and serious art style. You will be wondering which events are all in the protagonist's head and which really happened. They also raise the question, "Which concept of the self is the 'real' self?" 

Serial Experiments Lain and Perfect Blue explored themes and topics that are way ahead of their respective times. SEL and Perfect Blue get better as time passes by. The themes and topics become more and more relevant to our present time. 

Lain and Perfect Blue have a lot in common, starting with the theme of reality. Both make the audience question what is actually real, and both have storylines that might require rewatching to figure out. They are both highly psychological, and they are calm, but anxiety inducing, for the most part. 

Both are avant-garde pieces centered in Dissociative Identity Disorder, with a non-conventional storytelling, unreliable narration and the blurring of reality and fiction. 

Serial Experiments Lain and Perfect Blue are very different on many levels (mostly pacing, ost and themes). However, it also shares some important similarities that might make the fan of one love the other as well. -The main characters, while very different at first glance, really reminded me of each other the more I watched SEL. It is difficult to explain why without spoiling though. -One of the main themes of Perfect Blue is the identity, something also very important to SEL. Both shows will make you question what exactly makes us who we are and both will show the mc undergoing an identity crisis in a very interesting, impactful way. -Both shows play with the viewer's mind. The line between reality and illusion is blurred and until the very end, it is considerably difficult to fully proceed what is going on. However, the way it is handled makes for an immersive experience instead of a simple confusing mess. -Both shows have a very immersive feel, and the atmosphere is particularly well done. SEL is gloomy and disturbing since the beginning while Perfect Blue begins as fairly normal before gradually falling into madness, but both will give you a similar feeling of anxiety but also need to know more about what is going on. Overall those shows, as I said above, are very different. However I am pretty sure that if you liked one, you really might like the other. read more 

Both 90's psychological masterpieces. If you love one, there's no doubt you'll love the other! Lain and Mima share the same English voice actress too! Say what you want about about sub vs dub but Bridget Hoffman's work adds to the eeriness both stories thrive off for me. Both have a lot of philosophy to unpack, and outstanding visuals which feel so authentic to the era and are sure to bring about nostalgia whether you were alive in the 1990's or not. 

When you search in google for a good old anime titles, "Perfect blue" shows up at the first page, and I can admit that it was a very good anime movie. I also think that what most people say about this movie is correct, and most of it reviews say that this anime was "Strange, stylish and intelligent". Not many people know tho, that there is an anime from that times which was much more "Strange, stylish and intelligent" than most of anime we know these days, and it's called "Serial Experiments Lain" I can even say that things you'll see in this anime, are the pure definition of above mentioned words. If you like mysteries, psychological horrors, and more matured content, then check this anime. Since its not a full review, I can just add, that SEL is not a movie, but it's short 13ep anime which takes you more time on rethinking what you saw, than actual watching. Hope you'll fall in love with it as I did, have a nice day. read more 

Although the plots are not similar, both anime share similar and heavy themes, such as blurring the line between reality and illusion, identity, etc. Both are quite surreal and mind-bending. In a way, these animes were way ahead of their time and are more relevant today than have ever been. 

These shows are both psychological and they both have the same concept: What is reality? and what is not? Both Lain and Perfect blue show you how can media, Internet and technology effect reality and our world. Also, They both came out in 1998... 

Both anime show identity crisis, Dissociative Identity Disorder, and are very psychological. Perfect Blue starts out slow but the ending will blow your mind.  

Both "Perfect Blue" and "Serial Experiments Lain" are psychological anime from the late 90s that have garnered a bit of a cult following both inside the anime community and a bit in broader culture as well. Some similarities include: -both deal with a female protagonist losing her grip on reality -both are ahead of their time in addressing the dangers posed by the internet & social media -similar art styles -some rather unorthodox and avant-garde storytelling techniques used in both -somewhat confusing yet satisfying endings "Serial Experiments Lain" is more sci-fi centered while "Perfect Blue" is more psychotic and mentally oriented with more violence & sexuality. Still both are very influential animes and well worth checking out.  read more 

the ultimate schizo-posting. by the end of it you don't really understand what you just watched  

Serial Experiments Lain is definitely the closest comparison to Perfect Blue. They both have that uncanny sense of mystery, leaving the viewer feeling like there's more than meets the eye. We follow a main character whose vision of reality is unreliable, and the eerie feeling engulfing everything is something that stands out.  

same director(i think), different themes but both interesting strange stories 

Both are Satoshi Kon movies. Also if you look at Paprika and Perfect Blue both are very mysterious and deal with the question ''What will happen when dreams/illusions collide with the real world.''  

Both are movies by Satoshi Kon and feature a female main character that leaps between reality and fantasy, as part of the character’s job in Paprika and as part of the character’s personal struggle in Perfect Blue. Both movies have seemingly nonsensical plots with plot twists. Since Perfect Blue was made almost a decade before Paprika, it does look and sound more dated, technically and content-wise. 

Paprika + Perfect Blue = Paranoia Agent 

Both are Madhouse, Satoshi Kon films with a female protagonist in which the audience is manipulates to question what is really happening and what is just in someones head until the audience is bonded to the characters in that they are just as in the dark as they are. 

Both are great psychological/horror movies directed by Satoshi Kon. The dark but realistic style Kon is known for really comes to show and it works great with both these interesting stories with include delusions, mystery and many exciting moments. Before you know it, you'll be sitting on the edge of your seat! 

Both "Paprika" and "Perfect Blue" have quite deep symbolism and surrealism. However "Paprika" is much more higher all the way and in any aspect, in my opinion. I like how "Paprika" concentrates in itself all of Satoshi Kon favorite images and themes: 1) Like an escape from reality into a world of illusion 2) The devastating consequences of the invasion of illusion into reality and getting rid of these illusions 3) The sudden realization that the difficulties can be overcome, but turned to face them 4) Detective story filled with riddles and symbols 5) Surrealist paintings of collective and individual insanity 6) Adult man tired and lost in his past 7) Young woman who live a double life and hiding from all its second, the internal and true "I". But I think Satoshi Kon described these all themes best right here in "Paprika" (that's his last finished work, by the way, before he is gone). In my opinion this is his best work after all. Frankly saying, I don't like "Perfect Blue". I really liked "Paprika" much more. So, maybe if you don't like "Perfect Blue" too, try this one, I think you will not be disappointed. That's quite for sure. Moreover there are great qualitative soundtrack, beautiful and detailed, outstanding animation. P.S. Sorry for not very good english, it's my third learned. But I hope my recommendation will help somebody. read more 

Both have an adult woman as a protagonist and the plot starts thanks to their occupation (scientist(idol). The protagonist gets involved with something that starts to largely incovenience her whole life, mixing dreams/delusions with reality - confusing not only the protagonist, but also the viewer who has to figure out which parts are really happening in the reality of the story and which aren't. Both directed by same person. 

Both makes you wonder what is real and what is not, they play with your brain in an amazing level, full of Mystery, awesome Story and Characters 

satoshi kon, need i say more? but paprika is surrealism for surrealism sake. perfect blue uses it to create a story. watch paprika for trippy fun, watch perfect blue for haunting mindfuck. 

Both are anime movies directed by Satoshi Kon, and therefore, they have similar art and character designs. The plots of both anime have surreal elements, blurring the line between reality and reams, and character struggling with their identity.  

Twisted picture of the reality and playing with a viewer's perception. Apart from that movies don't really have much in common, but both are ofcourse very decent. 

A great touch of dementia, both main characters have a reality and a fantasy world. Directed by Satoshi Kon, really good movies. 

If you enjoyed Paprika, chances are you'll also appreciate Perfect Blue because both anime films exhibit a certain level of madness, as if they were written and directed by a surrealist painter like Salvador Dali. If you enjoy a surrealistic train of thought, both works are captivating choices. Their unique narratives and mind-bending storytelling will leave you intrigued and immersed in their bizarre worlds. 

Complicated For complicated Paprika and Perfect Blue have the same level, maybe because the author is the same person. Complications appear at the beginning of the climax and even to the end of the story. Character Development Another similarity, the two characters initially did not expect this to happen. Similarity of Character The two also have their other selves, Mima-rin with her Idol and Paprika with Atsuko. 

Both are dementia, psychological themed movies which will make you jump on the edge of your seat. You will definitely be on the last part before you understand what's going on. Even though they're dementia movies, both have a happy ending.  

both have a fairly similar plot 

Both are anime movies directed by Satoshi Kon. The plots of both anime have surreal elements, blurring the line between reality and dreams, and characters struggling with their identity.  

Go for it if you basically want to get mind f*cked. They both are made by same director and have lots of similarities like Psychological theme, female protagonist and adult cast... Plot is filled with lots of complexities and at the end, it's upto the viewer to presume what exactly happened. 

both are by director Satoshi Kon, so you'll probably like it. Having a psychological content, the two films manage to confuse and arrest you from beginning to end, leaving more questions open than providing answers. 

These two shows do not fear of showing the dark side of the entertainment industry without any sugarcoating. Idols and idol culture are pivotal elements in their plots. That being said, Perfect Blue offers more gritty and realistic spectacle in a movie format, while "Oshi no Ko", a TV series, has a lot of lighthearted moments that might feel a little bit childish for people specifically looking for pure realism. Nevertheless, both series don't try to hide anything what is wrong with the entertainment industry and the way society perceives it. 

Everything you get from Oshi no Ko is here (except the reincarnation part): stalker, media pressure & evil reporting, sex scandal, unhealthy competitive idol world, mental health, and many more. All the problems are here, just in a more serious dark way. Oshi no Ko will seems like childplay. WARNING sensitive content, not for everyone! 

Although the themes and objective of the story are different, the story itself is very similar to the prologue, although it focuses much more on the darker themes 

If you want a less romanticized and dramatic version of Oshi no Ko Perfect blue is up your alley. 

The story almost work together as an 'Idol' and basically similar, same goes to the direction of the plot but different set of times where Perfect Blue are focus in the 90s era and Oshi no Ko are in modern-day more likely the present-day.  

Both anime criticizes and have realistic approaches to the idol Industry. Perfect blue is a movie and it's older but, perhaps better than Oshi no ko, puts a rather exciting and harsh criticism of the idol culture that will make viewers worried about their favorite celebrities. By the way, I also recommend watching Oshi no ko, for its graphics, characters, and the wonderful music. 

Both deals about the dark side idol pop culture(yes, with stalkers involved). Perfect blue centers around a single idol's perspective while Oshi no ko continues to expand the perspective of how young kids are also affected in the entertainment industry.  

Oshi no Ko Really reminded me of Satoshi Kon's Perfect blue, Both explore the lives of idols in an enviroment full of lies, deception, and greediness, If you love one of these two, check out the other. 

Both Perfect Blue and Oshi no Ko touch on the toxicity of idol culture and the very harsh reality its performers face due to the industry standards. Even so, one of them is far better animated, written by a highly beloved author and received universal critical acclaim, while Oshi no Ko is written by Aka Akasaka and thus isn't as harsh on its critique 

It held the similarities on what is going behind the Entertainment Industry. Both show doesn't try to hide anything. 

Both have very similar themes, although Perfect blue is more on the mystery/thriller side. However they both deal with the issues in the entertainment industry, and society's conception of those working in such fields.  

- Both portray the lives of idols and the trials they are forced to face in the process - Both take a heavy focus on the theme of “lying” and “one’s true self” - Both feature deranged stalkers who live exclusively for the illusion of their ‘oshi’ - Both can get extremely graphic and disturbing despite starting off with seemingly harmless premises - Both show how the line between what is the “truth” and what is “fiction” can become blurred in the entertainment industry, especially with actors 

Both deal with corruption and problems in the idol industry 

both shows got me in the end. While watching both I thought I knew what was going on and thought I had it all figured out. Then BOOM!!! Near the end of both shows I was just like wtf?! what happened??? it got me thinking and made me appreciate the great stories of both shows. 

Satoshi Kon's style is wonderful, but to understand it at its fullest I think it's required to watch Paranoia Agent before, since it's the most simple of the "Mindfuck Trilogy" (Paranoia Agent - Paprika - Perfect Blue), and then get to the hardest ones. 

Well, Perfect Blue and Paranoia Agent are created by the same man, Satoshi-kon. Also this have a very very psychological content and essence. Anyway, two great works from a great man, Satoshi Kon. 

Both are directed by the incredible Satoshi Kon and tackle the mental breakdown of their characters, more so than Kon's other works. 

Both made by the best anime director ever Satoshi Kon, they both are centralized about the human psychology. Mousou dairinin is more about the broader psychology of a society then perfect blue is about one´s psychology of a young actor rising to the stars. You never really know what is real or not but one thing is for sure whatever one´s mind sees is important, and we humans are only creatures of the iceberg. and with both series it is the viewer who is going to interpret the meaning :) 

Both are directed by Satoshi Kon and are psychological drama horrors. They both have a real story blurred by the point of a view of a character, Mima in Perfect Blue and pretty much everyone in Paranoia Agent. 

If you liked the twists and trips and mystery of perfect blue you will like Mousou Dairinin. 

both great psychological horrors, dealing with similar themes of what your identity truly is/how you perceive yourself. also both directed by satoshi kon 

they both mess with your mind in a way. you think ones thing is that and it’s something completely different  

Both are psychological thriller anime made by Satoshi Kon. They are from around the same time and have similar visuals. They both start out being fairly normal but then branch out into being more abstract. They both have a lot of moments that are up for interpretation.  

Well, for starters, Paranoia Agent was done by the near-legendary (deceased) director Satoshi Kon, who was pretty much infamous in the industry for repeatedly making very artsy, psychologically complex titles that deal (harshly) with the "modern human condition". Working that angle, I would recommend you to try his highly-renowned movies, such as Perfect Blue. This movie deal with different topics than Paranoia Agent, but they are very well made, and you can see Kon's trademark twisted psychological style shimmering through in many places. 

This movie isn't as strong as Higurashi with the "Detective" part nor the plot twist but still it will make your brain feel like it was in a blender after you've watched it (hopefully, wont guarantee it though..). With it's physiological effect and mental instabilities you really feel like the character ARE suffering from the effects. 

Similar eeriness and bloodiness. Oh, and mind fuck. 

If you like Perfect Blue for its psychological horror that blurs the line between fantasy and reality, you are going to love Higurashi. Higurashi plays with your mind like cat and mouse, making you think and assume one thing only to be proven wrong by a twisted plot twist over and over again. This show is the definition of unpredictable. The first season is initially confusing, but trust me, everything ties together perfectly. Don't let your confusion drop this show for everything has a purpose.  

Both are psychological horrors, and if you really like solving mysteries and figuring out what is going on to see the final reveal I definitely recommend it. Has a creepy vibe and an unsettling vibe once you finish the first arc. Please watch the first 13 episodes to see if the show is right for you.  

Mental deterioration. The human psyche isn't the strongest thing in the world, it can be easily fooled or change abruptly consistently with ease. Sometimes, it can be so bad that it genuinely has a lasting impact on said individual. Higurashi and Perfect Blue are exemplary examples of such an idea. With an honest realistic setting quickly going to hell, the story Perfect Blue finds itself with former pop idol Mima on her trip in her own broken mind perceiving what is and what isn't. Higurashi follows a very similar concept, although it is more of the loss of mind altogether, with kids going back to tribal rages and aggressive attitudes. The two look as if you know that the cover is misleading, though the matter of how in its own juxtaposition of the initial setting, draws you to wonder the whys and hows. Both are good anime, I'd recommend them both for lovers of psychological anime. Take Higurashi for supernatural elements on the side, or Perfect Blue for a complete mind-break.  read more 

1. Horror 2. Drama 3. Psychological 4. Older style horror types not like the newer ones 

In both the main character(s) are slowly driven to dementia and paranoia, using a mainly first-person narrative which might deceive the viewer. If you're into being mind-blown, please consider watching both. 

Both of these have psychologically deep stories, reflect dark and uncomfortable realities, and opt for non-traditional ways of presenting their narratives. 

Metamorphosis. A disgusting reality is often one that pushes one to transform into the very same being the real world is made up of. Evangelion and Perfect Blue are both tremendous stories with that exact idea in mind to present. For NGE, Shinji becomes an Eva pilot to defend the earth from the terrors and havoc of the Angels. Perfect Blue pushes a realistic representation of what it means to change professions whilst also having a large following. From what was initially a good world, the change, be it, in or out of your control, still gives disastrous outcomes for the receiver, not everything can go your way, no matter how much you bend what you have. Two highly praised "classics", certainly worth watching if you love old-school stuff as well as psychological mind-warps.  read more 

While the plotlines are completely different, the darkness and psychology of both of these anime are on the same league. The use of music in PB also reminded me strongly of NGE. PB, much like Evangelion, has a dystopian, surreal, a bit schizophrenic feel however the most prominent difference is that PB has no lighter aspects as in the the earlier half of NGE.  

both deal with intense psychological themes and intense character development with the MC. 

Both titles contain heavy psychological themes that are guaranteed to mess with your mind and leave you pondering the thought of what you just watched for days on end. They both establish seemingly simple plots that ultimately change drastically throughout the anime and lead to darker plots with more depth than you may realize. I recommend this for anime watchers that enjoy shows that leave them on the edge of their seat wondering about what's going to happen next. 

it's one of the few shows/movies in the dementia category. like schizo-posting but for anime 

- Story about an actress life. - Chiyoko become actress to find her crush, Mima become actress to find her self. now which one you need to find first? your crush or your self? whichever it is, you'll have to move through events in life, both shitty and happy ones, before you can find them. both Chiyoko and Mima also experience this. - Satoshi's remark is very thick. you'll subconsciously make an assumption that both movie directed by the same person when you see the actress. 

Experimental character studies of deeply troubled individuals in the entertainment business, both got similar visual styles and gorgeous animation along with a similar abstract manner of storytelling 

Both movies are directed by Satoshi Kon, so they have similar art and character designs. They both deal with the lives of actresses, using a complex narrative that combines both reality and fiction. The main difference between them is their genre, as Perfect Blue is more thriller-oriented, while Millennium Actress is a drama. 

Both movies mix the reality with fiction so you never know what exactly is real. Both movies are by Satoshi Kon.  

Both blend the line between acting and the real world. Sennen Joyuu is a lot more happier while Perfect Blue is much MUCH darker. Same director and studio. Both great movies 

Both movies feature identity/reality crises. Both have horror/violence elements. Both are mind trips, forcing you to pause/think/rewatch to fully appreciate. Where Kara no Kyoukai is more epic/fantastic, Perfect Blue is more human/realistic. The art in Kara no Kyoukai is more attractive, while the voice acting (japanese) in Perfect Blue is more powerful. Both movies have top-knotch plot and presentation: go watch. 

Both are psychological thrillers featuring a female lead and a high amount of violence and gore. They are very dark and mature and will leave the viewer confused as to what is actually happening as the lines between fantasy and reality become increasingly blurred. If you're looking for an anime that blends horror and mystery these two will be sure to please. 

No other film stands in the way of non-linear storytelling other than these two—the fifth Kara no Kyoukai film, the grandest peak of the film series deals with themes of the distortion of reality and dreams, much like the premise of Perfect Blue, as key characters become entwined with the audience's view in a convoluted timeline of events. 

Mystery Thriller in which the main protagonist tries to find out the truth about their identity and the secret of the murder. The two movies feature similar schemes of warm color and use a lot of unexpected cuts and cinematographic shots. The non-linear narrative makes them confusing the whole time as viewers get lost in the sense of present-past-future and imagination-reality. 

If there is anything to connect specifically the EoE movie with Perfect Blue, it simply is the trippy presentation it holds. You will find yourself at the end of it all thinking, "what is this thing my eyes just allowed me to see". A good trippy experience.  

If you want another movie that absolutely stuns you physically and mentally from the harmony of brilliant direction, artwork, music design, and a mind**** plot, then 'Perfect Blue' is the perfect cousin to 'Neon Genesis: The End of Evangelion'. 

Both are disturbing and psychological which are confusing if not enough attention is given to it. Probably will take further research after watching both. 

Perfect Blue is similar to the first section of Memories, titled "Magnetic Rose". Both Perfect Blue and Magnetic Rose were made by Satoshi Kon(as director for Perfect Blue and as scriptwriter/art director for Magnetic Rose). Both are extremely dark and psychological. They explore the darkness that lurks within seemingly beautiful people. Throughout both, reality becomes heavily distorted as the line between past and present is blurred more and more. 

You will 100% like magnetic rose ,memorie's first movie.  

Both are gripping psychological thrillers with a compelling main character. You get the same sense of gritty reality from Monster that you get from Perfect Blue, they are based in our world and the events that take place seem as though they could actually happen. With well established villains who have understandable motives which is hard to come across now in anime. I feel as though Monster, much like Perfect Blue, is great for people who aren't too big a fan of action but they still want things relatively fast paced. Also for both their premise dosen't loose its intrigue and for the most part the story keeps you engaged throughout. I thoroughly enjoyed both. read more 

Both have fair amount of adult content or hinting towards it, and keep the suspense tll the end. 

Has great realistic animation with a serious but interesting plot with a great ending.This film is for a mature audionce 

Ever tired of the same art style and character design of today's mainstream anime? Getting sick of stupid character, bad dialogue, boring premise and incompetent storytelling? Well, Grandpa has something for you~~ No, I'm not old, at least not as old as Grumpy(RIP, man), but I am slightly older than EVA. And this is what I do when I exhaust today's pool of good anime, going back to the past to find some hidden gems, and some good gems I have here. Both anime take a realistic approach to their character design and art style which is almost extinct today. Although these two anime have totally different themes, the realistic style really fits them well to the point that it is difficult to image whether the anime will be as effective as in other art style. The talents behind these two anime are easily the best the industry ever has and they did deliver something really outstanding with good characters, clever writing, nice animation and soundtrack. If you happen to like some of the staff, like Satoshi Kon and Yoko Kanno, you may want to check these anime out as they are some of the earliest work they had done. I'm not saying that you should think these anime are good because they are old, after all you are entitled to your opinion and personal preference. But if you are someone like me who wants to see how anime can take in a direction totally different than today's anime, "Perfect Blue" and "Jin-Rou" are definitely not disappointing, and I'm just happy to share with you.  read more 

Both are very dark, grimy and don't shy away from showing violence and naked human flesh. And both have realistic design. 

Both include a female lead who looses their sense of identity and dissociates themselves from their reality.  

-MCs are in an idol group. -They both experience difficulties with their job. Although the backgrounds of the MCs are very different, the main plot points are very similar.  

Sure, it may be an odd recommendation, but Perfect Blue and Kite have a connection in characters being entangled in unholy situations, to the point where such come against their wills despite the efforts they can give forward. Perfect Blue does this with a stalker and hallucinations, a case of a mental attack. Kite does this with sexual moments and other disturbing elements, a case of physical attack. Both are pretty good in their respective genres, and something that deserves at the very least a try, more so for Kite than PB.  

Hell Girl and Perfect Blue do share the same reflection in the mirror to some extent. With one being about the journey to being broken, whereas the other is already at that stage, the two still resonate in their eerie, unearthly, spook to catch you out on how disturbing the world can get. An unfortunate chain of events, a cruel world, people out to do whatever it is to take whoever it is they want down. A sad fate for the two ladies of both anime. I'd follow Perfect Blue for an understanding of the internal chaos one experiences, otherwise known as insanity. I'd follow Hell Girl if you are looking for others of the same, only following down a path to hell, with the observer to witness it all unfold, a good psychological anime.  read more 

Uneasy, Disturbing, Surreal and a step too close to home. Steins Gate and Perfect Blue are both incredible psychological thrillers, they both play into the existential horror that someone, somewhere is not only out to get us but is watching our every move obsessively to maximise our suffering and paranoia. Okabe & Mima are not alike in their surface personalities or persona, Okabe is an ignorant, mildly perverted, self-proclaimed mad scientist. Where as Mima is a semi-respectful, sheepish Ex -Pop Idol changing careers to an actress. But where they both share a similarity is their believable and all too real sense of trauma, neuroticism and psychotic tendencies when they begin to realise that someone might be after them and the people they're close to. Another similarity with Steins Gate & Perfect Blue is just how confusing and uncanny everything can feel at times. Steins Gate chooses to go from uncanny and mind bending to eventually explaining what's going on and making sense of everything. Perfect Blue on the other hand makes nearly perfect sense towards the beginning but goes increasingly into the deep end the further you go in. Overall, two outstanding pieces of media that will not easily be forgotten.  read more 

They both are disturbing and have a similar style. Kanashimi no Belladonna is certainly more disturbing however they are both super well written. 

The infinitely better version of truth and reality articulated by anime. Perfect Blue is easily the best animated film i have ever seen, it executes the themes its trying to explore flawlessly. A disturbing and terrifyingly authentic depiction of inner conflict is what this masterpiece of a film offers.  

both female characters have insaanne character development 

Both mess with your logic and are very fascinating holding you to the end because it is very unpredictable what ode happen , Perfect Blue does not have as much blood as Tokyo Ghoul but has very disgusting and at the same time fantastic scenes because they contribute to evolution to the protagonist 

Sonny Boy is clearly inspired by Satoshi's Magnum Opus, Perfect Blue. The direction in SB closely resembles the style of PB in style and in content. PB and SB are works about finding and truly accepting yourself both with heavy psychological aspects. I found this anime series to be something that tried to be some kind of tribute to the memory of Satoshi, but in the end, it still could find its own identity. Nonetheless, it's really interesting to find that the original character design of PB and SB are done by the same person which explains why the artistic identity of both works are so close to each other. read more 

Both are psychological and get confusing if you don't pay attention fully to what's happening. Really serious and don't focus on visually pleasing character designs. 

They both fuck with your head, perfect blue is a lot more serious but they'll both have you feeling uncomfortable, in a good way. 

Both are psychological thrillers that give the watcher a lot to think about Both are pretty violent :0 

Both are thrillers with a stalker and mysterious murders with lots of psychological issues. Great artwork and some gore too. However, there are some big differences as Denpa Teki na Kanojo is a school life setting with a male lead & a harem theme to it as well, while Perfect Blue has a female lead set in the pop industry. 

Both are pretty creepy and will send chills down your spine on major scenes happening in the stories. While also having a slight sense of mystery throughout their runtimes. 

Again this will get you thinking. Personally I would recommend this over both ergo proxy and lain, but dont take that as you shouldnt watch those as well. If you have watched ergo proxy and lain you will like this too.
