The first half was very good (spoilers)
I liked the first half. It was creepy, and gave you a lot of questions to answer. It really gave the feeling of hopelessness.
Very rushed at the end... contrived (Doug=rapist) or predictable (sheriff), and none of the scares really scared me (the owl in the shed). There was the scene where the guy, for no apparent reason, lets Miranda steal his car. And then there was Pete running up at the last minute and saying sorry, and then not being mentioned again (?). Also, what was up with that random Tim ending?
Still, worth watching.
