How bad is it? It's the second-best David DeCoteau film - so it's pretty bad.
Should you see it? Yes. It's looniness actually works.
Judy Landers stars as an alien who does experiments on a nerdy college student, which turn him into a sexual dynamo. A dynamo with a rubbery worm-like phallic antenna when aroused, but it's still an improvement. Released by Full Moon, this is DeCoteau's best film after "Sorority Babes in the Slimeball Bowl-O-Rama" and came well before his films became just excuses to show men in their underpants. Not only scream queens Linnea Quigley and Michelle Bauer appear, but also porn star Ginger Lynn, Edy Williams and (briefly) Troy Donahue! It's a cheap tits-and-laffs film, but the humor often works and it's briskl paced.
