Both of these had a horror element, victims getting kill and such, Necronomicon has a very good mystery to it also, kind of like the movie 'Clue'. Mix that with hentai sex scenes = great !! Heartwork is more focus on whom is going to be the next killer. So watch both if u like a little thrill with your hentai =)
