Really, really good acting in an overall good film that you'll want to see again.....and then wonder why you ever even wanted to watch it in the first place. It is quite a disturbing piece of work and the camera is basically always shaky/unsteady, which may upset the weak stomachs. The theme itself is a bit disturbing too; teenagers placed in a mental hospital for their acts of violence/profanity....how lovely. Overall, a really good movie if you enjoy that type of film.
