Nice to see James Mitchum play the typical Spaghetti Western anti-hero who seeks revenge for his father's murder. He actually spends time dealing with rival bad guys as can be seen in other Spaghetti Westerns later. One thing I liked: James Mitchum's fistfights and brawls. Although there is a big gun-battle (with a high body-count) in a canyon, it is not a massacre, and it does not take place in the Grand Canyon.
