Jean Rollin makes movies that perplex 'movie viewers' - his films are always poetically surreal, hypnotic, absorbing, enchanting and hallucinatory, and almost never have a coherent storyline. This frustrates and alienates a good deal of viewers, while attracting others. His flix are about dream-like imagery unfolding, cascading in waves, nightmarish and bizarre. He's done away with the notion of a narrative or a linear storyline in favor of the visuals allowing the viewer to interpret as the viewer sees fit. But it's not traditional horror. Highly unconventional, I understand why most people don't enjoy his movies as well as why others are attracted to them. I've seen almost all of his flix and find something worthwhile in most of them while my wife hates them. Different strokes...
The other reviewer is too harsh on this film, expecting gore and nudity to suffice as entertainment. Don't get me wrong, I love exploitation in all its forms, but am one of the few who enjoys an Art House flick as well, and if we can incorporate both in one film, I'm in heaven, while most of my exploitation brethren are bitchin' and moanin'. There's enough nudity to keep most interested, especially the scene where the female leader of the vulgar ship wreckers masturbates on the beach while watching her cruel and sadistic followers brutally rape and kill two girls who re-emerge later on as spectres after making a pact with the devil. Have I got your attention yet?
