Jeremy Wilson’s review published on Letterboxd :
The Devil Inside is the kind of film that makes me feel like I was way too harsh on other bad and infuriatingly stupid 2012 horror films like ATM. This movie has to be the bottom of the barrel...for horror, for found footage, for exorcism/possession movies. For movies in general. Because if it isn't, I can't imagine what would be worse.
Seriously, screw this movie, its ending and anyone who managed to make a dime off of it. May their souls be taken possession by some of the demons in this film.
I'm sorry ATM, you weren't the stupidest horror film of 2012. This movie was it in a fucking landslide.
