Okay, so we've got Roberta Findlay ("Tenement: Game of Survival", "Snuff") directing a cheesy 80's horror movie revolving on a brotherhood of devilish monks sacrificing young women to Satan himself and drinking their blood in order to remain immortal. How bad could this possibly be? Correction; it's unquestionably going to be extremely bad, but the right question to ask should be: How is this not going to be entertaining? What we have here is pure late-80's trash-gold, with a completely nonsensical and laughably incoherent plot, tacky make-up effects, gratuitous nudity and a whole lot of gibberish about Our Lord Satan! The script of "Prime Evil" is wonderfully incompetent and aimlessly skips from one theme onto the other without any form of continuity. The film opens in the year thirteen-hundred-forty something with a bunch of monks turning to Satanism because they're angry with God for allowing the Black Plague to kill millions of people. This was obviously a brilliant career move because the story suddenly jumps forward in time 600 years and all the monks contained their same age and virility. But the next winter sacrifice is coming up and one of the cult members suggests using his granddaughter because she's still a virgin. Meanwhile, the leader of the cult engaged a convicted killer to randomly kidnap the granddaughter's best friends and then  finally  there's also a sub plot about a devoted nun going undercover in the cult by order of the Catholic Church. This last sub plot is actually the most hilarious, since Sister Angela is hardly ever mentioned anymore after her initiation rites. This is why I personally love 80's horror movies! There are so many ideas yet they all just loosely connect together. There's no atmosphere of suspense whatsoever and even the whole devil-worshiping concept seems redundant. They're just a posse of bloodthirsty priests craving to cut open voluptuous young girls. There's fairly little gore until the climax arrives and that reddish puppet with horns, supposedly representing Lucifer, is just plain pitiable. The acting performances are horrible, but I don't suppose you expected it any other way. Boring, however, it was not.
