Bret Easton Ellis' bestselling novel American Psycho, and Mary Harron's film adaptation starring Christian Bale, were created in the '90s to satirize the empty, consumerist "yuppie" culture of the time. More than two decades later, the story of Wall Street trader and depraved serial murderer Patrick Bateman has found a second life online, where culture can feel just as empty for completely different reasons. Maybe it's '90s nostalgia, or maybe all the memes come from the shock value, but there's one thing you can't deny — before there was Joaquin Phoenix's Joker, there was Patrick Bateman.
