Listen to the Stinker Madness Episode
Watch the Whole Movie!
When you cut in some psychedelia in the editing booth, your film isn't psychedelic, you just have a movie pile. Gas-s-s-s! misses the mark by about a mile, unless your goal was to one day have proof that the Baby Boomers were completely up their own asses and should never talk about other generations again.
The setup of the film is an interesting idea with the apocalypse coming and the meek inheriting the Earth - with one major problem, the meek are anyone under 25 and goosed on pot, free love and ego. From there you follow a group of bohemians travelling across Texas to a final destination of Barter Town.
