“I am enjoying the season of waiting.” This, from the lonely eldest daughter in Colorado’s Wilson clan, who has taken the oath to stay “pure” until marriage. Mirjam von Arx paints a creepily fascinating, though unopinionated, portrait of Evangelical Christians’ chastity movement, and the documentary would be hilarious if it wasn’t so terrifying. The height of the horror? The Purity Balls that now take place in 48 states.
