I hate pretentious movies that try so hard to be art that they forget to be entertaining. This movie falls into that category. I'm not really a fan of abstract surrealism at the best of times, but bleak self-loathing surrealism can just go take a jump in the lake! The trouble with symbolism is that if it needs a guide book to tell you what's going on (especially symbolism in movies where the viewer doesn't have the time to dissect every nuance), I think it fails. It just becomes a series of directorial in-jokes. I don't mind challenging film. I can stomach dark movies. But this simply failed to reward the effort.
Furthermore, none of the non-surreal relationships (Nicholas and Bobby, Nicholas and his mother, mother and boyfriend) were remotely credible, so my mind was constantly tussling with the disbelief about their relationships, long before the actual surreal stuff started happening.
This movie had the potential to be really worthwhile, with some mature performances from the young leads forging the way, but instead it disappeared right up its own self-indulgent rectum.
Read traymasters' review above, then save yourself the time of actually watching the movie. His review is far more meaningful and lucid than the actual movie!
