The attempt to look like a real documentation got me for about time, until an actor appears, that is presented as a former police officer. I must admit, that the style got me for a few minutes. But it wasn't completely bad from that point. I liked how the story developed. It's a sake that this story doesn't fill 1 and half an hour. It's kept short and that makes it more taut. After all it is not the worst idea horror movie makers had over the decades.
