Blood Tide(1982)

For a low-budget, occult thriller, 80's-era B-movie, I really enjoyed it, though I love occult thrillers as guilty pleasures. The direction is unexceptional but decent, the cinematography (easy, because of the gorgeous locales and mostly outdoor shooting) was surprisingly very good and the soundtrack was passable. I loved the casting, with Martin Kove (from The Karate Kid trilogy), James Earl Jones and Jose Ferrer (who always makes a great nasty, what with his cosmopolitan look, like Anthony Quinn, and his condescending, 'I'm better than you, and why do you think you can even exist on the same planet as me?' sneer and attitude), and, of course, the gorgeous women. Though the special effects were low-budget and quaint, they worked on this scale, and how they were executed. There's gratuitous nudity and sex at every conceivable opportunity (and a lot of inconceivable ones!) and even incestuous overtones, so it's terrifically entertaining, if not a cinephilic masterwork.

In short, it's worth a look, especially if you enjoy B-movies and occult thrillers, particularly from the 80's. It's both free online, or I found my copy in my legendary Mill Creek 50-pack, 'Nightmare Worlds'.
