Apple has the full trailer for the fourth entry in the Paranormal Activity franchise, and I’m happy to report that the creepy factor has upgraded from VHS to digital! The saga of Katie and Kristi and their freaky family continues, but this time, they’re freaking out a whole different family on camera. And we’ll all get to see it October 19. You can also view the three teaser trailers on YouTube, all of which are sufficiently spooky in a matter of seconds. (via iTunes Movie Trailers)
