American Psycho is a satirical psychological thriller film directed by Mary Harron. The movie is based on the novel of the same name by Bret Easton Ellis and follows the story of Patrick Bateman, a wealthy investment banker who leads a double life as a serial killer. American Psycho satirizes the excesses of 1980s yuppie culture and the shallow materialism of the time. The film uses dark humor and graphic violence to critique the obsession with wealth, status, and appearance. American Psycho's portrayal of a psychopathic killer as a symbol of the soullessness of consumerism offers a chilling and satirical commentary on the dark side of capitalism.
