Scott's stoicism serves well here as he plays a man haunted by the ghosts of his past, and by what he perceives as his personal shame. The film benefits greatly from Lee Marvin's outstanding turn as an old nemesis who may want one more shot at the former sheriff who imprisoned him, and who rather enjoys twisting the knife after someone makes an innocently hurtful remark. Particularly effective scenes include Scott's nighttime conversation with Gail Russell (the wife in the couple he assists on their road West), as he lies under their prairie schooner and she lies above him with the wagon's floor separating them.
The story proceeds effectively, steadily revealing more of the dangers facing Scott in his quest; the dialogue is particularly sharp and enjoyable. The men he pursues are not particularly memorable - certainly not nearly so interesting as Marvin - but the real focus here is on Scott's character as he finds himself affected by his journey.
Not a truly great western in the mold of Shane or High Noon, or the classics of John Ford, this is still a fine addition to the genre and very enjoyable and moving. 7 of 10
