I ran into this movie by accident, but I am happy I did. I must say that this movie is underrated, and in it's category - docu footage horror, it's one of the best I've seen. Unlike in Bkairwitch, where you are tortured for hours by yells and crackling sounds without ever seeing some actual horror scene, here you get your portion of horror. Gradually things go more intense and you try to understand who is good and who isn't.
The plot isn't much complex, but clear enough to make you enjoy what happens in between. The acting is actually good and believable.
For sure, I would not stay there for a day longer, as obviously things were not right there when a person disappeared, but they did stay... And that's why you have something to watch now:-)
The final was ok, but I would prefer a happy ending at least for one of the characters, still this way it's more realistic.
Life is not a Fairy tale after all.
