Leeches take no prisoners
25 October 2004 | by See all my reviews

Another of the many giant creature movies from the '50's, this one being somewhere in the middle of the bunch. This time, it's swamp hicks who are being menaced by leeches. Not just leeches, but big, mean leeches! I tell you, it's a load of cheese from beginning to end, but this is what one would expect from a genre movie of this era. It's a movie that leaves you asking, "why don't the fools just get a pound of salt and waste 'em?" Anyway, it's an OK effort with some decent acting. But those leeches, oh boy! The monsters are strictly tongue-in-cheek! So, B-movie fans should love this one, it's a wonder it took four years for this movie to make it to Mystery Science Theater 3000. In any event, proceed with caution into the boggy swamps of schlock.

** out of ****
