Tim here. Autumn is in full swing, Halloween is around the corner, and it's time for a visit from an old seasonal friend in the form of the Paranormal Activity franchise. 2015's entry, the sixth overall, is titled in full Paranormal Activity: The Ghost Dimension, and it's important for two reasons: it's the first one to be shown in 3D, and it's allegedly going to be the last one. Oh sweet Lord, please let it be the last one.
The 2007 Paranormal Activity was an exercise in brutal simplicity: sometimes, terrifying things would happen in a couple's bedroom while they were sleeping, and they had a camera set up to record all of those terrifying things for our benefit. It's as blunt and unfussy as three-chord rock. And all of the film's sequels have taken it as their primary goal to screw that up as hard as possible, adding layer upon layer of nonsense mythology, time travel, and a community of witches cultivating one family across generations to be the handmaidens to a malevolent spirit called Toby.
The Ghost Dimension takes as its stated goal the summation of all this mythology into one definitive chapter where all is explained. It fails, of course. Summing up the messy dog-ends of the Paranormal Activity pictures would have been beyond the scope of one movie, and given the increasingly arbitrary twists in the franchise, it would hardly have been satisfying. What The Ghost Dimension does manage to do is execute the reveal that all six movies have been building up to a tediously straightforward "find a body for the Devil" scenario, something that plenty of other movies have been able to sketch out in a first act, and not several hours over the course of more than a half of a decade. It's a damp squib of a finale if ever there was one.
