It's all quiet on the home front once again, picking up from the end of Paranormal Activity 2 .
Attempts to keep the franchise young – sparky teens (Kathryn Newton, Matt Shively), modern gadgets (including the year’s eeriest product placement) – can’t disguise the novelty wearing thin.
But this is a step up from prequel Paranormal Activity 3 , a rumbling ghost train of (nervous) giggles, fake scares and real ones.
Aside from the usual self-slamming doors and flying bodies, there are enough creepy kids and hiding knives to distract from a plot that’s increasingly mobile yet running on the spot.
