Common-type aquatic leeches grow to large size after feeding on steroid-laced blood of a number of college endurance swimmers, and then the nasty creatures lay siege to the entire campus for more.
This is by no means a good horror movie other than sitting around to make fun of it. My friends and I have entire bad horror movie marathons, just to get a kick out of how bad they really are. We watched this Wednesday evening and laughed and laughed. It's not so terrible it's unwatchable, but watch it if you love good "bad" horror movies. It's akin to the 70's movie "Frogs" for the modern age and is still as crappy. Still, it's watchable, unless you're a homophobe and are too insecure to handle shots of male chests and legs and the occasional butt shot. Most people rate it badly because of this, but since I am secure with my heterosexualness, I don't need to judge it solely on the fact that it seems to have gay undertones. (even though there's no gay couples what so ever)
