This was my first Jess Franco film and I saw it under the title "The Sex Demons." I remember it having a lot of the calling-cards of Franco's other films (although I wasn't familiar with them yet), including slow-pacing, ample amounts of nudity, and elegant/shocking imagery. At the time I don't think I could really appreciate Franco's films, so it's hard for me to say what I would think of it if I saw it today.
