This isn't a movie about public officials, 31 August 1999
Author: evilskip from In the swamp

Okay this movie sucks...literally.In some backwoods bayou a couple of poachers disappear. the locals think they're drunk but we know better don't we!There's some sort of varmints in the swamp!

A hot little tramp(Yvette Vickers in a stand out role)is running around on her lovesick/foolish husband. While fooling around with her wimpy boyfriend the hubby comes upon them with a shotgun. To scare them he herds them into the swamp.Well the swamp varmints come up and snatch the couple off in front of him.

Well the locals don't believe the story(especially the hero who has the personality of a deck chair).He's jailed where he promptly hangs himself.Before too long others start vanishing in the swamp.

There is a creepy scene of the leech's victims stacked up in a cave like human groceries.When the leeches start draining the blood of the tramp and others it is very effective too.

Problems with this fun piece of trash are numerous.The leading man is a real stiff.He has the acting range of a watermelon. The leeches while creepy also elicit some big laughs.You can see how the costume designer didn't take into consideration the actors would need oxygen tanks.Nice tanks.There also seems to be only two leeches due to a very limited budget.The townsfolk are pretty stupid and you can only wish more of them had fallen prey to the leeches.

This movie isn't a classic nor is it as bad as you've heard.A fun way to waste an hour!
