I enjoy most John Wayne films, notably his Westerns, and a long time ago read several books about him, but Wake of the Red Watch was all but unknown to me. (British TV frequently screens his better-known films butI can't recall "Wake" being shown before.)
It wasn't at all bad, if one overlooks some of the clichés and limited production values, and Wayne portrays a character more complex and less sympathetic than in any other of his films, even Red River and The Searchers.
Some of the plot twists were a bit hard to follow, and I'm still not sure about the relationship between Ralls and Sidneye - it seemed to mellow towards the end.
Before watching the film I hadn't bothered to note its date and, going on Wayne's youthful appearance and the unsophisticated aspects of filming and plotting, I guessed it was early 1940s. I was a little surprised to see that it was 1948, just as Wayne was about to film some of his greatest Westerns.
