This is pretty bad, even for a B-film junkie like myself. The most gruesome part for me was imagining "Liz Baby" coupling up with that husband of hers. Yuck! Maybe by swamp people standards he was prosperous and at least didn't smell like alligator poop.I will note that the scene of the leech lurching up to dine on a conscious but helpless Yvette Vickers did have a certain voyeuristic quality to it, but inter-species eroticism is just a bit too much.The creatures were really bad. Totally unconvincing and simply too anatomically absurd to not notice. And when shot, they voiced their displeasure through via a stock recording of what was evidently a very angry Persian cat. I wonder if they purr when content? I don't like giving these old sci-fi movies really low scores, but this one deserves it.

Here we go with another movie that doesn't make any sense.The only thing they don't fail at is letting us know who's going to die next.People are disappearing and the town people never believe those who actually see the "giant leeches".After most of the people are gone, they decide to believe the leeches exist and then quickly make up a bunch of "facts" about them.The hero threatens to arrest the elderly man who wants to use dynamite in the swamp to find the bodies but then ends up using it himself.Of course the elderly man is the hero's girlfriends dad, that's because the scientists don't have guns.Most importantly this movie has the obligatory scuba diving.What's a movie without scuba diving?Good?

While this film definitely ranks as a bomb (or should I say reeks), I must admit that I was very impressed by the speech that the hero makes in regards to why they cannot bomb the heck out of the ravine where an apparently giant leeches are living. Having scared the ferocious alligators away, they are spotted looking for lunch.Dealing with a middle aged husband trying to scare his trampy younger wife and her obvious lover, it quickly turns menacing when the husband witnesses his wife and her boyfriend being pulled into the marshes by something terrible. Sent to jail for their apparent parent murder, the husband probably hangs himself, little realizing that deep beneath could not quite so beautiful briny sea, the group of supposed victims are being munched on for a bloody snack for the actual giant creatures who crave fresh blood, leaving their victims with plunger like marks on their face as the way to die from the lack of plasma.Almost impossible to watch when you have to watch these leeches actually remove blood from their still living captives, this just becomes gross. It does happen on screen, giving this little explanation as to why tiny little leeches from the marsh are made huge simply by their reaction from the nearby Cape Canaveral. There are several major continuity mistakes, and the dialog is worse than rotten. Fortunately it is over in the hour, making that aspect of this of dreck all the more tolerable

Favorite Movie Quote: "Don't give me any of that crud about monsters."Ho-Hum. Yet more semi-hilarious Monster Movie Trash from the 1950s.A local, Florida game warden remains totally skeptical when confronted with tales of hideous, man-sized, blood-sucking creatures coming up from the swamp. Even the evidence of the bloodless bodies of some local yokels leaves him completely unconvinced.Only when he sees things for himself does he become a believer and decide to take matters into his own hands.Anyways - It's a good thing this flick was only 62 minutes long. I don't think I could have tolerated this junk for much longer than that.
