I have never seen this, but I googled it, and it seems like something I might like. Have you ever seen Requiem for a Dream or Pi? Both are directed by Darren Aronofsky. I LOVE his work. Requiem is one of my favorite films of all time. You should check them out if you haven't seen them already, you might like them. He also directed The Fountain, which was released late last year. I don't think it did very well in the box office, though. A lot of people don't understand or like his directing style, but I love it.
I never saw the movie, but the soundtrack was just about all my friends ever listened to, so I got to be pretty familiar with it. Some of the songs are really good.
