Even though this is a movie based on the recipe of "Paranormal Activity" it builds on the concept of the "found footage" sub-genre, and it takes it one step further. By combining footage of many cameras and points of view this movie is just the right combination of "first person witnessing" and actual traditional cinematography. The thing with this movie, is that even though you can predict the scary moments before they happen, you still get very very scared. This is the brilliance of this particular genre - and film ! By trapping the viewer in the scene of the "crime", and forcing him to experience first hand whatever the bad "spirit" wishes to "communicate", the viewer is affected even when he is certain of what is about to happen!. The acting is nothing special. I think the actors took it abit too far by pretending to be "real people". However, that is not damaging for the movie, since it is not the actors that are important here, but YOU the viewer ! I would recommend this movie to brave horror fans, and those who want to make their girlfriends shriek in terror. I would also recommend this though, to film students, as this genre has great potential!
