Director James Wan and writer Leigh Whannell, creators of the Saw franchise, target the junior high market with this PG-13 picture about a haunted house. The result manages to be both simplistic and incoherent: every shock is punctuated with a noisy, reverb-heavy sound effect to remind you that you’re watching a horror movie, and the story is one disconnected plot twist after another. Aside from some decent make-up on the ghouls, this is wretched even to look at. Wan aspires to the muted, ominous look of M. Night Shyamalan’s movies, but the shoddy blue-gray lighting makes this look like it was processed in dishwater. With Patrick Wilson, Rose Byrne, and Barbara Hershey.
