A suburban couple (Keri Russell, Josh Hamilton) and their two sons (Dakota Goya, Kadan Rockett) experience a series of strange and unsettling events. Are they the victims of haunting, demonic possession or alien invasion? Despite the overfamiliar trappings, writer-director Scott Stewart assembles some pretty effective moments—scenes of protracted suspense and several delicious chills—and he gets good performances from his cast, especially the underrated Russell. But the movie lists 11 credited producers (executive, line, associate and co-), and at least one of them should have noticed that Stewart didn't have an ending. The muddy, unsatisfactory fadeout spoils everything that went before; without a dramatic payoff, despite its good moments, the movie dissipates in the memory almost immediately.
