This movie is really about two very "able" smart men. And the actors could not have been better chosen. John Wayne and Richard Boone. Two of THE greatest, "fan" loving" actors ever; matched together in a pseudo "cowboy" setting; but with a modern slant.
It's gruesome plot is ensconced in family vs an outright "mean", atrocious outlaw; who is the the head of nothing but guns and goons.
The suspense, causing one to stay on the edge of one's chair, stays almost to the very end of a great movie.
So if you like comeuppance, true love, ego-led arrogance; with man-made justice, and action interspersed with drama; that will keep you watching intently; THIS is the movie "yuz" wanna see.
