Hulu’s newest true-crime documentary, “Demons and Saviors,” has arrived. The film, which premiered Aug. 3, tells the story of Christina Boyer, a woman who was rumored to have telekinetic abilities as a child and was imprisoned for the murder of her 3-year-old daughter as an adult. The documentary lets Boyer tell her story through a series of interviews conducted over the telephone, and features a variety of conversations with people who have often wildly different perspectives on her story.
