I saw this one on TCM this morning. I need to dig out High noon again and watch it. It's been about 2 years since I last saw it. I admit-I disliked the movie the first time I saw it--but it's been growing on me and I like it more and more--except for the thematic music. I still dont care much for the theme.
I think this may be a common thing as I too didn't think much of it the first time I saw it. The theme however has aged as well as the film itself.
I find Gary Cooper, similar to how I find Duke, always imminently watchable. I never get bored of watching either of their films.
