Cure
I feel as if this film took the rough concept Se7en and actually executed it better and with an even darker ending. Where the cruelness of John Doe ended, the evil of Mamiya is a cycle that existed before him and will continue after him and is much more hopeless and an empty ending from my perspective. I also have a feeling the opening scenes inspired Araki on how to hint at Yoshikage Kira before he was fully introduced.
