Ridley Tarantino’s review published on Letterboxd:
Sexy Sisters is one of many films where blonde actress Karine Gambier is masochistically tied up and abused mentally and physically by a brunette. I very much enjoy the film Franco made for producer Erwin Dietrich but apparently he stunted Franco's experimental camerawork. Their collaborations are always minimalist, polished and focused on erotica over statements or creativity. Thats fine. Sexy Sisters is one of the weaker of their films but it has decent dramatic plot, performances and great design on a dime.
