Church Ladies beware. The Satanic Temple in just six years has attracted more than 100,000 believers – including a sizable cadre in Detroit, which figures prominently in the film. It’s a movement that could be a religion, a cult, a self-help philosophy or a performance-art stunt, but is likely some combination thereof. Filmmaker Penny Lane’s mischievously entertaining documentary about the controversial Temple and its enigmatic leader, Lucien Greaves, introduces a rebranded version of Satanism for the 21st Century that has less to do with devil worship than civic engagement, social activism and savvy PR. Still plenty of demonic statues, though. Michigan premiere.
