I was raised Methodist. It still scares the "balls" off me. The innocence of Regan at the beginning makes her "turn" so shocking. It is a 'quiet' movie with "bursts"of the demonic!It disturbs me every time I see it and I have seen it 25 times!
I watch the Exorcist at least two times a year. It is my fave movie of all time.Poetic and shocking. It lulls you and then destroys you. I saw it a couple years ago in the theatre. It KILLED on the big-screen! "The Power Of Christ Compels You!"
