Update
Channel 4 finally showed this movie I've been wanting to see for ages, it's a Korean film called I'm A Cyborg but That's OK. and it's quite possibly one of the strangest, most touching films I've seen. It's about a young girl who gets sent to a mental hospital because she thinks she's a cyborg and refuses to eat/tries to kill herself. While she's in there, she's befriended by a male patient who goes round stealing other people's personalities/problems and he eventually saves her. It's got some freakily beautiful moments in it and it's quite surreal but I still quite liked it. I was watching it thinking, this is one movie Hollywood will NEVER be able to remake but then I thought maybe one of the weirder directors would give it a go.
