It’s that time of year again. For the third year running, the makers of Paranormal Activity are serving up another slice of the action around Halloween time. This instalment is a prequel to the first two films. I found the second film a bit disappointing as it was too similar to the first. I don’t think this will be a problem for the new film, as it is more of an origins story. Also it is set in 1988, and what’s not to love about that? Check out the trailer above; it is pretty scary. Paranormal Activity 3 is out on 21st October 2011.
