Trying to Listen to "The Exorcist"

Recently, I've been listening to "The Exorcist" as an audiobook. The main reason I got it was because I'm working on a novel that has demon possession in it, and I wanted to see how this mother of all demon-possession stories plays out.

I remember seeing the movie as a kid, but I don't remember being that scared by it. Of course, I saw it before I became spiritually awake to the reality of the devil, so I guess it didn't have as much punch for me then. Or maybe I'm just not remembering my feelings. I remember I felt more scared about getting caught by my parents watching an R-rated movie than I did about the subject matter of the movie itself. (In fact, it may have been the first R-rated movie I ever watched, when video players had just come out and my neighbors across the street became movie fanatics.)
