Since this is a Mexican movie i should be writing it in Spanish but i think the site only accepts English ones, okay here we go, the movie takes the fake documentary idea that was popular in the 90's and follows up and already wasted trend, the acting left a lot to add but wasn't nearly the issue of the movie, the movie's predictable plot adds nothing but what has been done by 100 other films already (especially in the found footage style) you can say is nothing else but another version of grave encounters which is why i am giving it the same rating.
Again without spoiling details, it has perhaps two interesting scenes but still fall flat and predictable in the same way that grave encounters did, with less ''scenes'' to mention in a way so is quite possibly that you even fall asleep on it in mid time, and expect similaries with the Blair witch Project in term of those scenes, not much else to add.
