40/100 Young woman stays with her uncle when her parents are killed and starts a relationship with the psychotic cousin while others make demonic plans. An extremely violent and gory opening had me totally interested in what was going to happen next. Unfortunately, it never reached that level again. It was dull with long, drawn-out sequences (cars driving, long walks or runs) and scenes of exposition and side plots that were simply filler. And that ending was awful. What's the point of everything if that's how you're going to end it? Looked nice, acting was fair. -- DrNostromo.com

**_Deviltry in the shadowy woods outside London_** A young woman with premonitions (Candace Glendenning) visits her uncle at his mysterious country manor (Michael Gough) where something tragic happens and she ends up staying to recover, getting close to her cousin (Martin Potter). But something weird and devilish is going on. Barbara Kellerman is on hand as the secretary at the estate. “Satan’s Slave” (1976) is a British flick whose plot is similar to "The Witches," aka “The Devil’s Own” (1966), and "Curse of the Crimson Altar,” aka “The Crimson Cult” (1968), both of which begin and end with occultic witcheries while the entire midsection is mostly slow rural happenings. It’s also comparable to "The City of the Dead" (1960) and "The Wicker Man" (1973). Like the latter, it throws in a couple sequences where a woman is shown fully nude (just a heads up). Meanwhile the satanic ritual scenes are reminiscent of "The Devil Rides Out" (1968). While this is the most obscure of these, it’s pretty much on par with any of them, although your mileage may vary. It’s the kind of flick where goat-sucking fools walk ancient manors or ominous forests in hooded robes and sacrifice naked virgins on sacrilegious altars. I’ll take “The Crimson Cult,” “The City of the Dead” and even “The Witches” over this but, don’t get me wrong, it’s better than “The Devil’s Rain” (1975) and "The Brotherhood of Satan" (1971). Winsome Candace Glendenning was 22 during shooting, playing a woman just turning 20. She’s reminiscent of Kathryn Hays, just younger by a couple decades. Meanwhile Potter has that brooding rock star look going on. The movie runs 1 hour, 26 minutes, and was shot in Pirbright, Surrey, England, which is just southwest of London. GRADE: B-

Sometimes trippy British superantural horror-thriller has its moments and seeing Michael Gough in a villanous role was fun, but the acting from the lead actress was rather bad, or I should say, bland.

Goat's Head Soup. Satan's Slave is a cult film, a horror pic for those with a bent for occult based euro trash made on a small budget. Plot has a young woman played by Candace Glendenning caught up in a devil worshipping cult run by her uncle Alexander Yorke (Michael Gough). It's full of the familiar tropes of such movies, plenty of nudity, violence and blood, and of course some interesting attire - gotta love those goat head masks! But it's all so tediously ridiculous and acted accordingly. Yes the violence is cold and nasty, and there's shock value here, including attempted rape, making this one that for sure would have had the censors of the time looking nervously through the print. But the interim passages of dialogue, of which the pic is predominately built, are borderline yawn inducing. Director Norman J. Warren is guilty of overdoing the horror cliche's, and the garish luridness of it all wears thin by the midpoint, but in the plus column is Les Young's intense colour photography. Cult fan base for it does exist, understandably so since there is a big call for this type of cinema, but with that comes the fact that it's an acquired taste and obviously not for all horror buffs. 4/10
