This is my first IMDb review, I'm not a native English speaker, and also have never believed that a review written by me could have any relevance; but this movie push me to it. I have no words to describe just how bad this movie is. This is that kind of works that try to be "experimental" and "deep" but just end being a flat, confusing, and just pointless movie. This plot seems to go nowhere, while the actors deliver performances that expresses less emotions than Data from the Star Trek universe.
Even if I try, I can't find any redeeming qualities to this work. It was Filmed with just one camera, in a location that became boring after the first 20 minutes. It got no peace, and near the ending it just loose it all, at that point the plot is a mess that doesn't carry any meaning. Maybe I should say the the music at the end credits is somehow neat (?). I wouldn't say that you must avoid it at any cost (movies that are this bad are a living testament of what not to do in a movie), but if you are looking for a movie to spend a good time (instead of torture yourself with it), you should look for almost any other movie in the world.
Also, don't thrust the tags of this movie, it has no elements of sci-fi (it's more fitted into supernatural genre) and the only thing that can classify as "horror" are some off-screen deaths.
