The 1973 release of "The Exorcist" took the moviegoing world by surprise. It was a horror film that shook viewers in a way previously unseen, offering a study of religion, terror, and the corruption of youth, and it became a visceral viewing experience for many. The picture was a major hit, and, as always, when there's success, imitators aren't far behind. Perhaps most notable was "Abby," a quickie 1974 endeavor that actually managed to irritate Warner Brothers, who sued to get the obvious rip-off out of theaters. Sneaking into the party is 1975's "Sex Demon," with writer/director J.C. Crickett using the basic idea of "The Exorcist" to inspire a no-budget replication for adult audiences. He does away with mood and character, cranking up the aggression in this peculiar effort, which aims to take the work of the devil somewhat seriously in the middle of obvious goofiness.
