Interesting! I was discussing the same topic with my room mates the other day. Exorcist certainly was one of the thrilling horror movies to hit the hollywood arena which boomed a box office clatter that even the great Alfred Hitchcock had to admire. My favorite Hitchcock classic is Psycho. He is at his best and provides a complex psychological thriller with deafening graphics and timid suspense. The subtelty with which he hits the theme and some real symbolic imagery makes Psycho a classic horror movies of all time. There is no second to the genius of Alfred Hitchcock and it is a testament to his crafts. It if important to note that the 60s did not have the modern flicks of graphics but with a little art this is a definite must watch for all horror lovers.
