Bone Lake

Morgan, whose previous films include the similarly twisted “Fixation” and “Spoonful of Sugar,” plays with her audience’s expectations as much as Will and Cin. She’s unafraid to shock with spurts of violence and gore, but restrains herself to use them only sparingly for maximum surprise. “Bone Lake” really starts with a jarring scene of a naked couple running for their lives, their relationship seemingly on rocky ground as one abandons the other in the chase. Some unknown entity is after them with a crossbow. They don’t make it, and their deaths are a series of painful ways to go. Morgan also uses the big lakeside manor as something of a funhouse, complete with locked mystery rooms featuring sex toys in one and a creepy, candlelit Ouija board in another, all to make Sage and Diego increasingly uneasy about their decision to stay with these strangers.
