I'm A Cyborg But That's Ok (2006) - 9/10
This is a magical film, made by director chan-wook park" (same guy as oldboy). It's a step in the opposite direction. A girl who thinks she is a combat cyborg checks into a mental hospital, where she encounters other psychotics. Eventually, she falls for a man who thinks he can steal people's souls. It is an absolutely magical little film, very well shot and the cinemagraphy / vivid use of colour made this stick in my mind since the first time I watched it. I urge anyone to give this a go!
