This movie was filmed with the intention to make the viewer feel that they were watching a "made at home" movie about a couple that was trying to get to the bottom of the strange occurances that were happening in their home while they were sleeping. To achieve this, the movie was puposely filmed as if it would be by an amatuer "at home film maker". Nicely done! This added, although the film was fictional, to the film's believability. The paranormal activity gradually intensified through the film as if the "nousance spirit" were getting more and more "powerfully ticked off" every night. This leads to a climax in the movie which I was witness to, sending movie goers over the backs of their theater seats!
