Fall will be here before you know it, which means the arrival of this season’s horror films. Yippee. And with that influx of fright comes the fourth installment of the Paranormal Activity franchise, due to arrive on October 19. The fourth film picks up right where the second installment ended — and not where the last one, the prequel, left us. As someone who has viewed all three, I hope this is not a lame attempt to capture the originality of the first. Diane Agron is cast as the principal player along with PN veteran Katie Featherston, who will most likely wreak havoc on an innocent, unsuspecting family. Of course, the plot remains ambiguous. Let the good times roll.
