When the creature from the black lagoon was released it later inspired writer Irvin Berwick to give birth to The monster of Piedras Blancas. The movie is basically a rip- off The creature from the black lagoon, but it still differs. For it's time the movie is pretty gory, showing several severed bloody heads and bodies with blood stains. Also, the monster may be frightening for younger viewers. A not very good movie, with a lack of the appearance of the monster and a short and plain ending.
