[Update 01/05/2022: Just cut out a bunch of garbage and need to redo this review completely.]
For the six hundred threescore and six people out there who haven't see THE EXORCIST the story is about a young girl, Regan, who lives with her actress mother in a very nice house in Georgetown. For the most part Regan is a normal girl, but when she starts to show small signs of behavioral abnormality, her concerned mother does the proper thing and takes her to the doctor. The doctor runs a million test, but none of them show anything. Regan's symptoms get a lot worse until it's evident that her problems aren't physical but more spiritual. A exorcist is called in and the rest is film history.
I could go on for days about THE EXORCIST about stuff that was left out from the book (ankle licking, the demon given a name: Pazuzu) and how the ending of the film went on for way too long, but Happyotter isn't really about film analysis, it's more about capsule reviews and in that regard I say Satan compels you to watch it.
P.S. Your mother sucks cocks in Hell.
Part 2 - Exorcist II: The Heretic (1977)

My favorite shot of the movie.
