The mood and character set-up are pretty good here and there are certainly some nice scary parts. However, what I think totally sinks the film is that director Bertino never sets up a good sense of space. About halfway through the film I realized I had no idea where the characters were in relation to the house from one scene to the next. They seemed like they were in this very big house, but we only get to see like two or three rooms in it. Then, a barn is introduced halfway into the film that it's not clear how far it is from the house. I lost track of where Tyler and Speedman were in each scene and thus lost interest in their predicament. But, still didn't totally dislike it. More like a missed opportunity.
