Walter Brennan and Dack Rambo played a grandfather and his grandson who roamed the old West searching for Jim Sonnett, Brennan's son and the boy's father, a legendary gunfighter. This was a thoroughly routine western, shot on the cheap, with nothing to set it apart from countless other westerns. Will Sonnet's catchphrase, "No brag, just fact," got old after the first 10 or so times you heard it. While Brennan was always interesting to watch, Rambo didn't make much of an impression, and the only remotely "original" aspect to the show was how the writers would figure out different ways to have Will and his grandson come close to finding Jim, but always managing to just miss him. The show only lasted one season. That was enough.
