It's a movie I watched years ago, once, thought it was ok, but never thought too much of it. Then everyone started talking about it, so I'd like to see it again now that I'm older.

But based on my memory of it and bits and pieces I've seen since then, I'd say it's just a story of a guy who loses his mind. Not much more. A guy predisposed to schizophrenia who experiences some sort of trigger that sets him off.. and with that comes the self destructive behavior, contempt for life, etc.

If you want to see movies that are profound in the way they present deep, dark, underlying themes, there are surely much better. American Beauty was pretty heavy...
