Let's fix those "ambiguous" endings, shall we?

Nobody has ever satisfactorily explained what is supposedly "ambiguous" about the ending of "No Country for Old Men," which has one of the most exquisitely judged denouements in movie history. ("A Serious Man," too.) So, what is it, precisely, that some folks need explained or resolved for them? The smartly funny video above imagines what would happen if "The Wrestler," "Lost in Translation," "NCFOM," "The Graduate" and "The Sopranos" gave the literal-minded exactly what they desire.
