I think "Fight Club" is already a classic! At least all the people I advised to watch it love it as well. Not only is compelling and powerful, but also thought-provoking and visually creative. My favourite part is when Narrator visits his totem animal (the ice cave scene) and later finds it substituted by Marla.
It is also one of the few movies which are better than the novels they are based upon (same happens with "A simple plan", and I love its sarcasm. I really did not understand all those critics who said it encouraged violence or it was fascist. I mean, what I though after leaving the cinema was not exactly: "Cool, let's enter a terrorist group" or "Great! I'm creating/joining a fight club right now" but "Oh my God, let's hope things never go so bad".
