Has some decent jumpy scares and plenty of action in the last 15-20 minutes, but I thought the teenage angst bit was stretched a bit too much, and the film lost some of it's scariness due to this factor alone. The ending felt rushed and a ton of things were "explained" using unnecessary flashbacks, which could have been unfolded earlier and that could have helped the film to stick to it's original plotline. As things stood, this ended up being a teen film for the most part, with a horror twist/cameo thrown in.
A decent watch, but not very impressed.
