I never thought I'd live to see the day when there was a good spaghetti Western. Most of the ones we have rammed down our throats are those goofy ones Eastwood was in, the ones where men are classified into gods who can't miss, demi gods who can only miss gods, and mortals who just fill graveyards. Yawn provoking one dimensional caricatures they think can pass off as caricatures because they don't shave.
But this one combines the elements of credible characters with entertainment and an actual story line.
It helps to have Guy Madison, too. No doubt he had a large say in keeping this one from being a cartoon cardboard cut out.
Not saying it is realistic. This is a shoot em up. But the circumstances are more thought provoking and believable, because the characters actually have motivation. In the spaghetti flops that clowns like Leone directed, he simply made everyone a certain degree of a sadist to explain their actions. In this film we are spared that cliché of the modern movie. The gun play is far more believable than anything Leone ever did. There are a few clownish fight scenes with people doing flips, but not many.
Like most good Westerns, the minor characters and their treatment with dignity make this stand above the lesser ones. Again, one sees this a lot with Guy Madison, so either he had a large hand in it, or he was careful in the selection of the role.
This is entertainment.
