Masturpiece! Jess Franco was a prodigious film maker, expert at every aspect of it's many tasks. No, he isn't Tarkovsky or Bunuel, he was something different. Just check out his resume on IMDB. One thing that makes his porn stand out is emphasis on close-ups of women's faces; an erotic aesthetic that sets Franco's work apart/also casting, framing, and so many other little things that make a Franco film not JUST porn!
