It is the average to not so great 'political' artists such as Spike Lee that NEED to be TALKING politics as he rarely if ever says succinctly or successfully with his craft what he begs to communicate to the people. Then he DEMANDS to be noticed and rewarded in his craft DESPITE his lack of brilliance and lasting impact of his work as a filmmaker/writer.
The Cohens focus on their work and let the work speak for itself. And so it does and this is what they are noted for. Notice too how succinctly, honestly, and intelligently they make their political point and move on to what they love to do--make films.
And the Academy Award goes to . . .
Very astute observation. Well done.
