This is a surprisingly competent horror movie, and it is certainly better than most other films of the same genre. That having been said, since very few horror films work for me, it should come as no shock that I found this one to be nothing more than an average movie. It did generally keep me entertained, and there were some clever moments in this film, but the momentum did not last all the way until the end, and so I'd say that it falls a little short of being "good".
