i dunno if there has ever been a more perfect match of novella with director than No Country with the Coens. that story brought out the best in them and they brought out the best in that story (seriously, i love that book, but the movie is even better).
there's a coldness to Ridley Scott's oeuvre that would superficially seem suited to adapting McCarthy, but the secret of McCarthy is that he's actually very good at making you emotionally invested in his characters without you even realizing it's happening, and with Ridley i feel like that if that happens, it's more by chance or casting than anything. also, i feel like McCarthy's narratives on paper have an intimate, pinpoint type of focus to how they are described and Ridley has always been a stylist that's more about mood and largesse. McCarthy's heavy on mood, too, but it's a very precise thing with him and with Ridley it just isn't.
also, McCarthy writes worlds that, if they are to be shot, should be shot on film--that texture, that contrast. or at least digital that looks like film. it's pretty off-putting to me how digital this movie looks in the promo stuff. when i saw the trailer in the theater, that didn't help, either.
