Another picture I think is a good representation of Fight Club is this one. The movie constantly focuses on cigarettes and cigarette burns but not only that, the carton of cigarettes has the rules of Fight Club on it.
I really disliked Fight Club. The movie as well. And most of Chuck Palahnuik's books too. I find his ideas to be cynical beyond reason, and the book itself devoid of any characters I sympathize with or truly want to follow. I find Palahnuik's world view far too tainted grey and black than it actually is, and although dramatizations and exaggeration can be useful in illustrating points sometimes, I find he takes it far beyond the extreme into the unpleasant and unecessary.
