A film which, once it finally gets going, is tense and questioning. For much of the early section, however, the story about a couple grieving and escaping from a miscarriage is a bit of a plod, which never then really ties up with the rest of the narrative. When the set ups half way through the movie start paying off, things get much better. The deserted location, zombie threat and psychopathic peril are all added to by a modern feel. By no means indispensable, but worth getting through the sluggish beginning.
