Most critics are frightened by it. The praise falls almost entirely on the same few things: the fixed camera in the bedroom, which has viewers scanning the frame for anything out of place; the sound design, which makes a creak or a thud stand in for effects; and the two leads, whose performances several reviewers find believable enough to sell the found-footage conceit. Several also credit Oren Peli’s patience in holding a shot well past comfort.
The reservations are about the shape rather than the scares. Slant finds the storytelling too schematic and the explanations unnecessary, while Empire and HeyUGuys both think the final stretch abandons the plainness that made the earlier scenes work. Several critics warn that it only works if the viewer plays along. The Hollywood Reporter alone tips negative, finding the slow build a test even though the scares eventually land. The spread is otherwise narrow, from strong recommendations to qualified ones.
