All films take a certain suspension of disbelief.
Fight Club takes perhaps more than others, but if you're willing to let yourself get caught up in the anarchy, this film, based on the novel by Chuck Palahniuk, is a modern-day morality play warning of the decay of society. Edward Norton is the unnamed protagonist, a man going through life on cruise control, feeling nothing. To fill his hours, he begins attending support groups and 12-step meetings. True, he isn't actually afflicted with the problems, but he finds solace in the groups. They fight each other, and then as others are attracted to their ways, they fight the men who come to join their newly formed Fight Club.
