I am Jack's complete lack of surprise
Fight Club is one of the most twisted movies on the market. The teaming of Edward Norton and Brat Pitt was incredible. They both have such quirky personalities that they bring to their characters. The film has some very clever ways to present an idea, I loved the effects that they incorporated into the film while the characters are either explaining things (eg. the IKEA apartment scene, and the airplane falling apart description).
While the film is both Crime and Drama I think that it should also be labeled under dark comedy as well as there are so many great lines and things that happen that make this just one of the better movies out there.
