What Rio Bravo says about both.
I'm not sure what the dig on something called "the left" is about: "Wayne has always been close to a comic-book version of American power in all its swaggering crudeness". I'm sure politics does inform some of a person's reaction to Wayne, but he's always been more complicated than the caricature above suggests. To say that being of "the left" somehow blinds a person to this is ridiculous. So ignore the third paragraph and this is a fine appreciation of a classic movie.
