I think this movie can be called the movie of misdirected rage.

The characters of Joe and Bob were relics of the WWII generation who didn't quite understand their kids opposing the war, taking drugs and listening to rock and roll. But I think their real rage was at the fact that America was beginning her long decline from the heights the war left her at.

"Joe" himself is a low-rent Archie Bunker, ranting at all the things that have made him angry, living his life of quiet desperation, until he teams up with Compton, a guy who wants to avenge himself on the hippies who ruined his daughter.

Honestly, most of the movie looks silly, the characters are worse than one dimensional, they're laughable. Peter Boyle was capable of better stuff.
