I saw the film today and it should earn an Oscar for Sean Patrick Flanery who plays the possessed criminal. Exorcist Father Carlos Martins calls Nefarious the best film on exorcism ever made. The demon engages in manipulating mind games with the psychiatrist who is evaluating the sanity of the possessed man in order to determine his fitness for execution.
Demons do the same kinds of things with exorcists, revealing secret sins and exploiting their weaknesses. This is not a horror movie. Rather than sensationalizing the subject matter, the movie takes a serious look at the reality of demonic activity which has increased because of the dechristianization of western society. Pray that this movie is successful and sends many to their knees in prayer. St. Joseph, Terror of Demons, pray for us.
