'The Death of Stalin:' Comedy plus cautionary tale?

When leaders have absolute power, they act absurdly. That’s the take in the new movie “The Death of Stalin.” It’s about the power grab in Russia after Joseph Stalin died and stars Steve Buscemi, Michael Palin, and Jeffrey Tambor. “Veep” creator Armando Iannucci directed it.
