So, we're giving the classic Edgy Catholic horror film from 1973, The Exorcist, the highest edgy rating of Off The Edge and the highest Catholic rating of Totally Catholic. The Exorcist includes some totally shocking scenes of demonic possession which include nearly unspeakable sexual things done by the possessed to herself with a crucifix. Hard to imagine something more edgy than that! And as for Catholic, what is really great about this movie is that when science can provide no explanation for the girl's condition, and the protestant clergy can provide no remedy, the family turns to the ancient Catholic Church for answers, and Catholic priests are the heroes.
The Exorcist is the classic example of the Edgy Catholic Supernatural Horror category. Totally Edgy (perhaps too edgy) and Totally Catholic.
