Gas-s-s-s, or it became necessary to destroy the world in order to save it

This started life as a serious science fiction movie, but relatively late in the day Corman decided to transform it into a wacky comedy. He dispenses with his usual tight construction, and the almost non-existent plot chronicles the activities of America's youth after the adult population has been wiped out, with many of the themes and characters from his earlier movies turning up in a caricatured form. It may sound promising, but thanks to Country Joe's tedious score and an endless succession of feeble jokes, it is likely to be of more interest to Cormanologists than anyone else.
