Ed Rants - Paranormal Activity 4

So just been shared via Total Film's website is an infographic meant to promote the DVD release of Paranormal Activity 4, my nomination for the worst film I saw at the cinema last year because I was smart and didn't go to see Keith Lemon.

The basic point it's trying to make, so I gather, is that it's trying to prove with SCIENCE that this must be a good horror movie, the numbers say so!  As someone who understands a lot about statistical mathematics, scientific testing and film criticism, I can't help but have a few questions to raise about this graph.
