Books by Bret Easton Ellis that are turned into Movies can go either way. On one hand, American Psycho is just pure enjoyment. On the other hand, The Rules of Attraction is sort of annoying, although it has some great scenes. The Informers is based on a book of short stories about depressed, emotionally vapid, trust fund twentysomethings in LA. So expect a soundtrack with New Order, plenty of lines of coke, lots of humping, four distinct strains of Chlamydia, and maybe even a vampire.
