While Unknown Dimension offers plenty of insight into the making of the Paranormal Activity films (seeing as I'm a huge fan of the series) and some rare behind-the-scenes pictures and videos, it doesn't really deliver much in terms of deleted scenes / unseen footage aside from what comes up in Parts 4 & 5. It opened up a lot of doors and then all of them slammed shut. Not to say that the film is bad, I just expected more footage, specifically scenes that were cut out and used in the trailers, but I think it's as good as it gets. I've haven't seen the latest PA film, but I'm sure that one didn't fare any better than this documentary. That being said, it's worth a watch, but don't expect too much out of it.
