The scenario may be familiar to anyone who loves the genre, but thankfully writer/director Scott Derrickson executes the familiar beats well. The movie is nothing special, but it works and after an August packed with absolutely insipid horror fair like The Possession and The Apparition, functional horror sounds pretty good right about now. The acting is decent, the set up creepy, the scares plentiful, and the pay off effective. It doesn’t revel unnecessarily in goopy gore and the filmmakers actually attempt to tell a story. Sure, there aren’t many surprises (especially if you’ve seen the poster which gives away the ending), but at least there’s one perfectly watchable Hollywood horror movie slipping into theaters in time for Halloween.
