Black Swan
Holy shit I LOVED this. It definitely reminds me of perfect blue and I'm sure some major inspiration is there but holy shit this is so good. It’s like a psychological and body horror movie. Also a prime example of psycho sexual done right (along with Lynches films like Blue Velvet and Mullholland Drive). It is one of the best demonstrators of extreme obsession leading to self destruction (like annihilation; another Natalie Portman movie) along with another favorite, Whiplash. Aronofsky is a genius.
