Ti West’s slow-simmering “Beware of Satanists!” cautionary tale looks and feels like an artifact from the early 1980s, found in a dusty corner of an abandoned video store. A naive college student takes a babysitting job at a creaky Victorian house, working for a couple of shady characters (played by veteran cult movie weirdos Tom Noonan and Mary Woronov). Before the literal all-hell-breaks-loose third act, The House of the Devil plays up the spooky atmosphere and retro style – right down to a scene involving a cranked-up Walkman, a song by the Fixx, and our sick fear that everything’s about to go very wrong. NM
