I can't say that much that none of the other posters have said but I must say I love this film. I've read the book and it's well executed and written. The film is good too but people dismiss it as a horrible adaption of the book. This is, more or less, true but only because instead of filming it as a bleak, passive movie they put some heart into it. For example, Julian is only a character hinted at in the book. We only meet him a couple times before we realize from many vague clues that he might be dead. In the film, we see his friends really trying to help him. In the end, I have to stick up for this movie. I don't know what it is about this film but it just works for me. Just realize that had the film been a faithful adaptation of the source novel you would have been completely and utterly depressed by the end of this movie. I understand that was the point of the book but... well they gave it some heart.
