This movie is fantastic. Brad Pitt might have the best performance of his career in this. The entire movie I was waiting for the wow factor, thats what was missing for me the entire time, but Fincher delivered one of the greatest wow factors in any movie ever. It was brilliant. The one flaw for me is that it didn't get me to think as much as i would have liked it to, or as much as another Fincher movie, Zodiac.
