Jeremy of We Got This Covered wrote, "It takes a lot for a horror movie to really piss me off and yet The Devil Inside does that in its short 83 minute running time. Never have I seen a horror film with such potential piss it all down the drain with one of the worst endings in the history of film. I can’t really call it a bad ending, because there really isn’t even an ending to begin with. The film coasts on bloody scares that are ripped off directly from other, better films, and yet it still sort of works, but then the screen goes black and you’re left with a partial film. It’s the biggest dick move ever by the studios and I doubt they care as long as they have your money."
