I have never really been a fan of either Documentary or especially Found Footage Horror. But, the way this one builds the tension and suspense, it does the job just fine. I'm probably just a BIG P\/$$y, but quite honestly this scared the living $h!t right out of me into my pants (probably more information than you wanted...)
Anyway, despite my usual antipathy for these kinds of films, once in a while one will come along that is very effective, and this is one of them. Coincidentally, I also recently watched a similar film called 'THE ATTICUS INSTITUTE' which also scared me $h!tless, but that one was much more heavily slanted toward the Paranormal than this one was.
So, there really is not a whole lot to say about his particular Genre except whether it is done well or not. And, I can say that for me personally, I was absolutely RIVETED to the screen the entire time. There was NO down time on this one. And YES, there are numerous jump type scares, but with this kind of film, I think that it would be obvious that that comes with the territory. The point is whether the jump scares are done well, and they are indeed...
My imagination is VERY sensitive, so maybe this film would be more intense for me than for others, I don't know. All I know is that by the end, I was frigg'n creeped out. So, what that means to me is that the primary elements that are vital to a film like this, namely the mood and atmosphere, are clearly effective and doing the good job that they are supposed to be doing. Like I said, this type of film is not my first choice. I tend to find the more Fantasy based, 'fun' type of Horror more enjoyable (like 'NIGHTMARE ON ELM STREET' or 'RE- ANIMATOR', for example) But, this one seriously had me by the nuts and refused to let go...
I would say that if you don't mind the Genre, and if have an active imagination like I do, and if you can REALLY get sucked into a story easily like I did with this one, then this movie should indeed scare you...
