I saw this movie....The actor that played the possessed prisoner was very good...
He was stating his case from the point of the demon so it was revelatory. Certainly many people need to hear this. But the other main actors and cast were of a lesser quality and quite pedestrian. The low point of the movie was at the end when Glenn Beck was supposedly interviewing the psychiatrist who "treated" the possessed prisoner. GB must have financed this because his big mug on the screen was very "cringe"- there was really no good reason for him to show up in the film. I would give it a 5 out of 10 rating.
