Rated R, for good reason, and at just over 1 hour, seemed a little short. No noteworthy stars, producer, or directer. The ending seemed a little abrupt, but was actualy a fine ending, in my opinion. I saw quite a few continuity errors, but I was looking for them, kind of my pet peeve.
The director really tried to make it seem like a real documentary. Minus the continuity errors, he did a fine job. A few times the "realness" was broken, again mostly from the continuity errors. The movie showed some real potential at the beginning, but as the movie went along, it failed at meeting that potential.
It is not a movie I would call scary, just kinda gross. I was only scared once, but that was one of those cheap scares, a barking dog during a conversation outside. Some of the movie I found humors, in a strange way, some of the spoken dialog from the possessed people was just comical.
Not a movie to see in the theater. It might be worth it from RedBox. And if you have the chance to watch it for free, go for it, as a last pick.
