There’s been a recent crop of cult fiction books like Justin Taylor’s The Gospel of Anarchy and Fiona Maazel’s Woke Up Lonely, to Paul Thomas Anderson’s Scientology-influenced movement called “The Cause,” in his 2012 film The Master, that has started popping up. Even though these works undoubtedly deserve your attention, you really can’t beat the real thing, especially when it comes to cults. You get plenty of that with the new documentary The Source Family.
