Dennis Vehlen’s review published on Letterboxd:
There isn’t too much to say about ‘Satanic Sisters’ aka ‘Sexy Sisters’. The cast is made up of Franco regulars like Karine Gambier, Pamela Stanford and the always good Jack Taylor and Eric ‘Stileto’ Falk. It’s pure sexploitation and even though it’s a fairly stylish and good looking movie, there isn’t much in the way of story in between endless borderline hardcore sex scenes to keep you interested. Franco made this kind of movie and story (trying to drive somebody insane to get their money) a number of times, and sometimes better. Unless you’re a total Franco fanatic, this is one you can probably skip.
