The movie's not a western in the usual sense. Instead, it's more like a pondering of character and life-styles set in modern Mexico. Manuel and Maria are in an arranged marriage, she being passed along like a piece of property, he being a budding farm entrepreneur. They are above all "respectable", and the feeling is that this is what holds the marriage together.
Then, into their settled life arrives escaping train robber Santiago. But he's not a typical robber. We know that from his buddy's moving death scene. There Santiago shows something of a poetic sensitivity, proving he's not without his own sense of values. In fact, he's more a free spirit than a criminal type, even giving away much of his loot to deserving strangers. Ironically, however, he appears unfree to be anything but free!
It's Santiago's free-wheeling effect on the young couple's brittle marriage that makes up the storyline. Kennedy, of course, was one of that era's premier actors. Here, his bravura performance effectively dramatizes Santiago's free spirit gusto. On the other hand, as the young couple, Iglesias and St. John appear over-the-top at times. Perhaps that can be rationalized by their emotional release from repressed lives. Nevertheless, the emoting does at times distract from story advancement.
The notion of respectability is also pondered here. What the screenplay seems to be saying is that conforming lives are okay as long as one's humanity is not sacrificed in the process. In his own eccentric way, this appears the lesson Santiago imparts to the young couple. At the same time, religion gets much the same treatment, while criminal Santiago acts poetically as a kind of secular priest in easing his dying confederate into the great unknown.
All in all, the movie's distinctive features come more from blacklisted writer Zimet's offbeat screenplay than from cult director Ulmer who's required to film in Technicolor instead of his b&w forte. Nonetheless, the movie's fully deserving of the Ulmer brand-- an offbeat 80-minutes that manages some depth over and above its tacky 50's title.
