This is such an unpleasant film to watch. Christian Bale brutalized himself for the role, needing to lose so much weight. It's about a man who is beset by guilt and is unable to sleep. I was astonished by the fact that three previous viewers mentioned Raskalnikov from "Crime and Punishment." Bales' character is beset with paranoia and lives life, thinking that everyone is trying to do him in. He has a terrible time with relationships. But there is something that happened in the past that he is carrying around. He finds a woman who is willing to have a relationship with him, even though she's a prostitute, but he messes that up. We watch him self destruct and try to fend off threats, but he is his own worst enemy. Very good film.
