How bad is it? It's a Larry Buchanan film. That should be warning enough.
Should you see it? Of course.
As if Roger Corman's AIP films weren't bad enough, Larry Buchanan remade four of them as a package to sell to southern drive-ins and local TV stations. This is not the best or worst of the four, a remake of The She Creature (reviewed earlier on this blog). Past life hypnotic regression causes a girl to become a sea monster in a rubber suit with an obvious zipper. In fact, the same monster as in "It's Alive," another Buchanan film and not the Larry Cohen cult classic. There's an air force parapsycholgist. There's two musical numbers, one about Batman, one sad one that causes spontaneous riotous dancing. The film was shot silent and dubbed in post-production, it's underlit, has continuity errors, every scene ends with a fade, all the attacks are off-screen and the scenes are shot mostly from a distance with one close-up per scene.
