Wes Craven was a horror legend, responsible for some of the genre's most iconic films. Most notably, he helped to establish the slasher film with 1972's Last House on the Left and 1984's A Nightmare on Elm Street. As if that wasn't enough, Craven went on to redefine the genre again in the 1990s with the meta and irreverent Scream. Even his less successful movies, like Swamp Thing and The Serpent and the Rainbow, make for fascinating experiments.
