I viewed this on Tubi, which is the kind of place you'd find movies of this ilk. Seventies exploitation to be sure, with all the baggage that that moniker entails. There's a wisp of a narrative, something about a housewife being selected by a devil-worshipping cult to be their queen. Attractive cast, especially lead actress Linda Christian, who capably handles the material, such as it is--and The Philadelphia Story it ain't! Since this was filmed in 1972, we get the usual barrage of groovy fashions and home furnishings, a treat for fans of retro stuff. The synth score is a double-edged sword, irritating in some scenes, but rather atmospheric in others, particularly the black mass scenes. These scenes are probably the most compelling in the whole film. Over-ripe monologues, moody lighting, and the previously mentioned score (augmented by some eerie Gregorian chants) all make for some effective viewing. The DP and cinematographer both must have had a purple fetish, because there are several scenes where that particular color is emphasized. Maybe the director was shooting for an art film aesthetic, with some of the kooky angles, shooting a dialogue scene through the gauzy veil of a poster bed, etc. Looks great in the Code Red transfer, and doesn't overstay it's welcome
