I rented this movie totally by mistake thinking it was Claude Chabrol's "Blood Relatives", but it didn't turn out to be a TOTAL waste of a rental fee. It's kind of an early "erotic thriller", but unlike those films it doesn't let itself get totally overwhelmed by long sex scenes and actually does function somewhat as an inheritance thriller with some horror movie scenes involving graphic brain surgery thrown in for good measure.
French actress Lydie Dernier was living proof that you didn't need to be able to act or even pronounce the English language if you were willing to doff all your duds in any piece of crap movie defecated by the low-budget Hollywood film industry. This is definitely a step up from "Satan's Princess" (and let's not even speak of that movie she was in Robbie Benson). Naturally Lydie takes her clothes off a lot, and this is the only film I know of(aside from that dubbed late-night Ursula Andress cable classic "The Sensuous Nurse")where a woman seduces a son, a father, AND a grandfather (the latter played by the late, great Ray Walston).
Would I have rented this intentionally? Well, no. But I have now wasted five minutes of my (admittedly pathetic)life reviewing it, so I guess I can't say its THAT bad.
