I ain't afraid of no ghosts. Except in the Paranormal Activity movies.
Most sequels devote themselves to moving the story of a franchise forward; the Paranormal Activity movies seem to be going in reverse. As fans of the hit horror series may recall, the first film took place in 2007 and involved the haunting of a seemingly ordinary San Diego home shared by yuppie couple Katie (Katie Featherstone) and Micah (Micah Sloat). Paranormal Activity 2 turned the clock back roughly a year and introduced us to Katie's younger sister Kristi (Sprague Grayden), whose own house and family were bedeviled by the same poltergeist. And now Paranormal Activity 3 time travels two decades into the past back to 1988 when Katie and Kristi were little girls (played by Chloe Csengery and Jessica Tyler Brown respectively) living in a picturesque Carlsbad, California split-level with their mother Julie (Lauren Bittner), her new boyfriend Dennis (Christopher Nicholas Smith) and -- you guessed it! -- the same violence-prone ghost. At the series' current rate of regression, by the time we get to Paranormal Activity 5, we'll be back in the silent film era and the characters will have to hand-crank their personal cameras Thomas Edison-style.
