Yet another faux documentary horror film, and like all faux documentary horror films it's a disjointed, padded, boring, unscary mess. There are a few potentially decent scenes, mostly ruined by the fact that you can barely see or hear anything because of the intentionally out-of-focus and shaky cinematography and quiet dialogue. The story itself is utterly unoriginal, managing to hit every note of a very tired subgenre.

It particularly fails as a horror film. Any tension that may have existed is killed entirely by the lengthy sections of characters walking around spouting uninteresting dialogue about the the details of possession, exorcism, and the church.

All of this is made worse by the truly terrible ending. The last third of the movie seems to attempt to make up for the dearth of content prior by jamming in an entire film's worth of plot and events. The rushed sequences lack any meaning or tension as they pass before you have much time to be scared. In truth there isn't even an actual ending. The film resorts to that cheap and lazy technique of suddenly stopping without bothering to resolve anything. All it offers in return is a half-assed attempt to sell the audience the line that it's all actually real.

In conclusion, if you want an exorcism film just watch The Exorcist again. That's all these exorcism films ever attempt to be, and they all manage to fail hilariously.
