Earlier, someone mentioned "A Clockwork Orange". I agree with that one too. Not so much for the violence or the brutal imagery, but for what it made me feel. I hated Malcom McDowell in the beginning of the movie. I mean, HATED. I wondered 'how can I possibly root for this "hero" in this movie'. I wasn't prepared to sacrifice my sense of right and wrong in order to allow this punk to continue to derive pleasure from the pain of others.
Then, after his "treatments", he changed. And so did my feelings for him. I actually felt sorry for him when he returned home and found his parents had replaced him with a "new son". (Plus, they killed his snake. Jeez.) My heart broke for him. This guy, whom I hated so much about about 30 minutes earlier, was suddenly a sympathetic character. I have never seen a film totally make me change my opinion/perception of a character so well and so completely.
By the end of the film, (when he returns to delivering that evil, creepy "smirk" directly into the camera) I felt like the rug had been pulled out from under my feet. He was back to his old self, and I was sufficiently disturbed. More at the thought of what he would do next than what we had already seen. Simply an amazing emotional ride.
