ah the 70s, gotta love em. looks to capitalize on the jaws craze by bringing the terror in the water to the inland waterways. throws in a government/science gone wrong twist and you get a cross between the 50s animal horror flicks like ants and the 70s/80s stuff like jaws, swamp thing, and toxic avenger. a few t&a moments per the usual. overall a decent little horror flick.
