Similar themes of a main character having conflicts with change and both venture into a mysterious plane/realm of existence w/ another character roughly their age. There's too many other similarities that I cannot recommend this alternative enough.

Gurren Lagann shares the same levels of plot insanity while omitting the "horror" and "psychological" aspects. While GL has a more comprehensive story, the action of Getter Robo Armageddon will satiate all the shonen bros out there.

Here's a military drama with great narrative pacing, brilliant voice acting, amazing action sequences, and a fantastic script for the majority, if not all, of characters involved. Honestly as one of the best anime ever made.

An anime military drama that has a very tactful placement of plot devices that reveals its bewildering world to the audience little by little. An anime that does require conscious focus on subtle details which reveal a larger & gorgeous picture of the anime's reality with each episode make for a mindful watch. The music is especially fantastic as well.
