Jesus Franco directs and stars in this story about a crazed ex-priest who witnesses a series of staged "Black Masses." Convinced the participants are possessed by Satan, he kills them in order to "exorcise" their demons. Although this storyline has a lot of promise, numbingly repetitive dialogue and Franco's amateurish acting keep the film from reaching its true potential. It's also padded with numerous sex scenes-featuring suggested autoerotism, bondage, sexualized torture, lesbianism and an orgy, among other things-none of which serve to advance the plot. The result is a film that tries to be both porno and horror film, but doesn't really succeed at either.
On the plus side, this DVD from Synapse Films features several worthwhile extras, including the first-ever commentary by Jess Franco, an alternate opening sequence, the trailer from the heavily-cut U.S. release (titled "Demoniac") and other goodies. According to the liner notes, this film was restored from a number of different sources, so you see color shifts and slight jumps throughout the movie. It's slightly annoying at times, but nothing major. The monaural soundtrack is less than perfect (not uncommon for rare, older films like this) but doesn't detract from the viewing experience too much.
Two out of five stars.
