El Stupido! Warning...nothing to redeem.
14 July 2002 | by michaelRokeefeSee all my reviews

This Mexican project was dubbed for American release as SWAMP OF THE LOST MONSTER by K. Gordon Murray. Filmed in shades of creamed coffee this claimed horror flick lives up to being called one of the "World's Worst Movies". A man disappears from his coffin before he is even buried. He had the misfortune of being killed by a mysterious lake dwelling gilled-man/creature. The extremely low budget helps this to be a laugh riot instead of a scream fest. You owe it to yourself to at least watch long enough to see the dime store monster from the deep! I don't know if being loaded with a six pack of Mexican brew and an atomic burrito would help this stinker terrorize anyone.
