As much grief that I have given Cartoon Network over its programming choices and practices, I do have to give them credit for being brave and airing Aaron McGruder's "The Boondocks". Tonight's episode imagines Martin Luther King returning to the world only to find himself completely estranged from the world. As he finds that America has largely turned away from the values he championed -- and even worse, he finds that black America has stopped trying to reach for the dream, but rather have decided to wallow in gross decadence. If I had to guess, this is the episode that most personally captures how McGruder feels about the world -- and he'd give that final speech as spoken by King to his peers if he felt that they'd listen to him. However, his plan B -- to put it in a cartoon -- is as good an backup as any.
