I liked the basic scientific/supernatural ideas offered here, and I would have found the film a lot more interesting if it stuck with and developed them. Why has this girl become attuned to otherworldly messages and how can electronic devices be used to monitor supernatural phenomena? That's good stuff. Unfortunately, the thriller aspect of the film is the least successful, and that becomes obvious as those elements begin to dominate the plot in the third act. If you can't figure out who's behind a series of murders in the area in just a few minutes, then you're a really bad judge of character.
