An idiotic scientist decides to turn himself into a walking catfish monster. He also wants to create a new race of fellow walking catfish monsters. This is a horrible movie. It starts off with some laughable narration and an awful folk song. It only gets worse from there. That said, I was cracking up a lot throughout this thing. There's one golden moment shortly after the guy has changed into monster form. He's walking through a basement and clearly trips over something, perhaps the shitty monster costume itself. We're also privy to the long, drawn out process of him getting his machines, pulleys and other junk together for the mutation. This takes up about 20 minutes of screen time all by itself.
About halfway through the film, we get more awful singing from a bunch of hippies, followed by a march to the local jail. The so-called hero of the picture is a joke. He and his girlfriend also wear ridiculous red jumpsuits. They should have just stuck with the college guy and the sheriff, not that doing so would have saved the movie or anything. This is currently #10 on the IMDb bottom 100 list. There's no question that this is a bad movie, but I wouldn't rate it that low simply because of the amusement I got out of it.
