Riding in the wake of Jaws, Blood Beach makes an attempt to frame the sand – or more precisely a creature therein – as the antagonist to fear.
…aaand it by large fails to do so. It is very hard to take this particular threat seriously.
On the positive side the movie itself, along with its early 80s beach scene and detective cast led by the late John Saxon and the Burt Young are all sufficiently entertaining to watch. All in all, Blood Beach is more of a mystery what dunnit story rather than a horror movie.
