The storied history of Mystery Science Theater includes many, MANY cheap rubber monster suits... and somehow, some way, Sting of Death may have the worst so far. MSTies might recognize director William Grefé as the director behind the MST3K Season 2 experiment Wild Rebels. You'll be happy to know he made Sting of Death first, so Wild Rebels was a movie he made as an even more experienced filmmaker. As an added bonus, this movie also features the aptly titled "Do The Jellyfish" by Songwriting Hall of Fame inductee Neil Sedaka. Does this tune warrant TWO extended dance sequences? Probably not, but it is an earworm that will still be drilled into your head long after the credits roll.
