This film will scare you. It's an unpretentious, yet very well made horror that builds a genuinely creepy mood and introduces us to likeable characters we really care about. I have seen it several times and I have found it enjoyable every single one of those times. The interesting thing is that the film is based on real events, but that is also a potential problem, because the filmmakers cared more about putting together an effective screenplay than remaining true to actual events. This is no docudrama, but a film that takes great liberties. However, they are justified, because the screenplay they ended up with was pretty much flawless. You won't forget this film.
