A great and disturbing film.

Rating: 10/10 (5 June 1999)

Although probably not the scariest film ever, this may well be the greatest horror film ever. It has lingered in our minds for more than 25 years because of this. In its savage and brute force as a horror film, it achieves excellence. The quality of Linda Blair's performance at such an early age makes it even the better. And yet so few people realize that this film is based on a true story. The book by William Peter Blatty (who also wrote the screenplay) is based on actual events that happened at Georgetown University in 1949. So, in conclusion, this film is really not your average horror film, but a look into the struggles between good and evil.
