The movie started out good, had some action and suspense in it and was reasonably well done and creepy, worth watching at least once, but near the end it turned into some weird vampirish Underworld ripoff, so that kind of threw the movie off.
The thing with a video documentary and found footage movies is it's supposed to be somewhat believable, like made to look like it was real, but this film was too unrealistic to be believable to any point.
But it's definitely not the worst film I've seen, it's not too bad, so it's worth watching at least once, with all that said.
