As you can tell from that joke of a synopsis, this was pretty much just another Paranormal Activity movie. It had the same home video look/filming. It had the same slow but creepy build. It had the same rapid set of scare shots at the end. But then they did some weird thing with a mystery door that somehow brought you back to the first movie and then the movie quickly ended after that. Rarely have I heard a theater say what the hell out loud like they did at the end of this one.
Although anyone who is a fan of these movies is going to see this regardless, I wouldn't really recommend anyone bothering to waste their time with this. It was just more of the same with a very annoying and nonsensical ending that didn't have anything to do with the overall story.
