What really goes on inside a cult? Over the past couple of years our collective fascination with that question has risen to a fever pitch. The literary world obsessed over Emma Cline’s The Girls and Stephanie Oakes’s The Sacred Lies of Minnow Bly, both of which re-imagine collective madness as coming-of-age tales. Indie auteur Ti West barely bothered to alter the Jonestown story for his horror film The Sacrament. Unbreakable Kimmy Schmidt turns a young woman’s survival of a doomsday-sect kidnapping into screwball comedy, and American Horror Story: Cult pulls everything from Andy Warhol’s Factory to Heaven’s Gate into its maniacal vision.
