The film earned a "two thumbs up" rating from Richard Roeper and A.O. Scott (filling in for Roger Ebert), with Roeper saying, "This is a cool little thriller with big scares and fine performances."[REF] .
Some criticized the change of atmosphere two-thirds of the way into the film, when the initial pacing and action morphs into that of a "run-of-the-mill slasher horror film" [REF].
