An excellent cast, excellent directing, a creepy setting and methodical realistic detail paid to the mystery of a strange corpse makes this one of the most effective horror movies I've seen of late. Each and every scare and fright is earned, there's no over reliance on overused techniques with the exception of one highly telegraphed cat. No CG-fests, no over-the-top visual feasts, just a slow building dread that culminates in horror. Suspenseful and riveting, this movie starts strong and only builds from there. Certainly not for the particularly squeamish, but there's no real gore beyond elements of a clinical autopsy. Its best knowing as little as possible about this movie before going in, so I will simply leave it at:
