A guy who doesn't really respect women, falls in love suddenly. That relationship ends (I won't spoil it by telling you how). He then becomes self-destructive, behaving badly, looking for fights, even with his friends etc.
It's described as an 'indie' movie and I've never really found out what that means. It's told slightly in flashback, it doesn't really have a sense of humour, and the main character is conceited before he falls in love, happy for the brief period he's in love, and then aggressive and rude when it ends, so it's hard to feel for him.
I think it's meant to be a study of people and relationships, kind of anyway. The guys father is James Caan, who plays someone who has never had respect for women, and his son was the same, but ends up changing.
Eventually the guy meets someone, who seems really nice, and it all ends quite fluffily. But I was never sure what the movie was trying to put across. I can imagine some people really liking it though, it's well acted, not too long, and the people involved do convey emotions well.
