“The Blackcoat’s Daughter” (1/2 out of four) was a practically worthless thriller set at an all-girls boarding school about two girls (Emma Roberts and Kiernan Shipka) bound together by a series of events involving disappearance and murder. If you went to school with people like these, no judge could probably convict you for turning homicidal either. So incoherent you could probably watch this movie backwards and it would make just as much sense but it’s also lifeless and boring. Striking noirish cinematography by Julie Kirkwood is film’s only plus and gives this half a star.
