Jeremy of The Daily Rotation wrote, "It’s really hard to review a movie like The Devil Inside, because it’s not really even a full movie; it’s half a movie. The film begins in familiar exorcism territory and just when it starts getting good it abruptly ends. I’m not exaggerating in the slightest; it literally goes from mid-scene to end credits. It’s not the kind of movie that tacks on a rushed 15 minute ending that was obviously forced on by the studios for sequel purposes. Oh no, The Devil Inside just ends mid-movie. The characters are in the middle of doing something that’s important for the films story and it just ends without any resolution whatsoever."
