How bad is it? It's intentional camp that fails.
Should you see it? Probably not.
This horror comedy almost works as both, but ultimately fails at both. It has Joe Franklin and Jackie Martling - and if you recognize those names, you already know more about this film than I do without having seen it. A high school break-in puts toxins in a pool, turning a high school swim team into flesh-munching monsters. Then a heavy metal band comes to the rescue. Some of the gore effects are better than the budget makes one expect and the intentional humor sometimes works, but mostly it looks like a time capsule (and a not very interesting one at that).
