If a critic says The Exorcist is the best movie ever made, then I say that critic can’t really take that position without the story having something to do with it. The Exorcist is not so special a movie that someone could think it the best movie ever made without the story playing some part in why they like it.
The problem is, the story is theologically illiterate – and utter garbage into the bargain.
The Exorcist is a thinly disguised child-rape fantasy, written by a strange person who really dislikes children.
You don’t think so?
Read my extended essay on the novel and the story the novel demonstrates. I explain, using many examples from other movies and novels, that the author of The Exorcist hasn’t a clue about the psychology of fear and wrote a novel which might reveal more about his character than he intended. I make the case that the theological ‘motivation’ for writing The Exorcist could easily be justification after the fact given how much child-rape imagery is in the book.
The book was so successful that nobody is going to admit what is obvious to anyone who reads it and can just state the case openly.
