John Wayne has got to come out on top when facing down a bunch of "bratty" Harvard students. However, I have read he was firmly rejected by some hospitalized Vietnam soldiers who did not experience his visit as authentic. I think people loved the characters he played, and by association, the man himself. Actors often come off second best when they wade into current affairs, especially war situations. The real combat vets, James Arness (Anzio) and others mostly seemed to avoid advocacy, or at least exercised restraint, to their credit. But John Wayne did wonderful work on screen. It is a rare scene where he doesn't command the center, even when he's just to the side reacting. He was a natural.
