I read most of the reviews here, but saw the movie anyway because I like Westerns and Janice Rule, and I especially enjoyed two other Fred MacMurray Westerns, "Good Day For a Hanging" and "Face of a Fugitive." The latter is a classic in my opinion.
Most of the movie was worthy -- the stars, production values, general story outline, dialog. It held my attention. But, I have to agree with most of the reviews here: there were long, boring, repetitious stretches. There were too many indoor talky scenes. The cattle drive scenes seemed small, cramped and cheap. There were hardly any scenes involving action, excitement or suspense.
My biggest complaint is that the movie consisted mainly of repeated boring scenes where Jeffrey Hunter's character declined to fight (with fists or guns) his adversaries. Some branded him a coward for this, but the way the scenes were structured, it seemed to me like a smart move to avoid meaningless, risky fights.
