Rotten Tomatoes Score: 33% (5.1/10) Box Office: Though it cost just $3 million, Knock Knock's limited release has only seen it raise $3.518 million worldwide to date. It's very much the sort of film to thrive on VOD, though, so it'll make real money soon enough. The Verdict: While critics praised the three central performances, they also took umbrage with the familiar plot (though it's worth noting that the film is a remake), and frequent divergences into flat-out absurdity, which clash with the pic's otherwise savage tone. Still, with its beautiful women, a hilarious turn from Keanu Reeves ("chocolate and sprinkles!") and a demented narrative that throws out a few interesting curveballs, it's an intriguing curio all the same.
