This is a crash-budget spaghetti-western (with open references to films by Sergio Leone) disguised as a post-apocalyptic action film ala "Mad Max" or "Escape From New York". Apparently the whole world has been reduced to gravel-pits, because the whole film takes place in one after another of these - a sure sign the budget allowed for zero set design. There's no point in trying to pretend it's a good film.
However, I should note that there is some good in it; whether enough to warrant a viewing is debatable - let the buyer beware.
First and foremost is that the director, having decided he was going to make an action film using only funds and resources he had at hand, has done a rather remarkable job of keeping up traditional action-film pacing throughout the film. This is largely thanks to camera angles and editing. We get rapid intercuts between close-ups of struggling hands, full-shots of bodies blowing apart, long shots of an over-all battle area - with very little excessive flashiness masquerading as 'art'. These guys intend to sell some tickets, period (and, at the time of 1st release, were actually successful at it). These film-makers either know what they're doing or are really trying to learn what to do (more likely). They certainly deserve points for effort.
Although the characters are all one-dimensional, the actors manage to flesh them out somewhat, even Fred Williamson. And the cars are silly and kind of fun in a dumb way. But it's really the pacing that saves the film.
Hey, it's late at night, you had to work over-time, you're over-tired, you wanna crash with a cold drink and numb out before a forgettable action picture - well, this could be the one.
