 According to the reviewers, Jack from "Fight Club" and Brandon Teena from "Boys Don't Cry" share the following:
Fight Club careers from one resonant satirical idea to the next without quite deciding whether its characters are full of crap or are Gen X prophets. Jack and Bob subscribe to a new form of male bonding: They cling to each other and sob. When Jack's apartment mysteriously explodes--along with his carefully chosen IKEA furniture--he moves into Tyler's squalid warehouse and helps to found a new religion: Fight Club, in which young males gather after hours in the basement of a nightclub to pound one another (and be pounded) to a bloody pulp. Fincher and his screenwriter, Jim Uhls, seem to think they've broken new ground in Fight Club , that their metaphor for our discontents hits harder than anyone else's.
 A fascination with masculinity
 An unsupportive family  An addictive personality  A fascination with masculinity  A sleep disorder
