Theatrical vs “The Version You’ve Never Seen.”
Devils, demons, pazuzu, deception. How do people get possessed? Different theories.
Supernatural detective work. Priest losing his faith.
The Catholics. The Rite of Exorcism. Bureaucracy. Serious vs loosey-goosey exorcisms.
Occam’s razor. Science.
Tradition. Latin as the language of ancient evil. Ecclesiastical latin.
Medicine -> fringe medicine -> call a priest!
The ways this movie is timelessly excellent and scary. Parenting.
Demons might not be the best at planning, OR we might be inconsequential nothings to them, OR creating a rift between god and his people is their job.
