I'm sad and rather baffled that the Russian government is taking this series to be a negative commentary. Yes, there were some idiots in positions of authority, but name me a country where that is not the case. Yes, the government was far too secretive and paranoid, but that was a different time, a different country, a different government - so why be so offended?
Mostly, to me, this series is a love song of praise to and awe at the almost unimaginable sacrifices all levels and sorts of people made to repair the damage of the exploded reactor. As Craig Mazin says repeatedly in his commentary, "They did it anyway," even when they knew it was possibly a lethal risk - Shcherbina, Legasov, other scientists, the generals & other army people, the miners, the plant workers, the conscripted men and women who "liquidated" the problems. It's breathtaking, heartbreaking, fills-me-with-faith-in-humankind stuff! (And I don't often feel that way.)
I wish the current government would focus on that part, which in the end is the biggest message, not just the idiocy and denial that a much smaller group gave in to. To put the blame on the CIA is mind-boggling - how on earth could they have made Bryukhanov, Fomin, and Diatlov make such a boneheaded series of decisions? Made the grid in Kiev unable to allow the test to go forward as scheduled, and count on events playing out as they did? It just does not pass the laugh test. I suppose they'll try to lay it off on a bomb, which presents many others issues - also not credible.
Anyway, I don't know when a TV show has made me think this hard, read so much, want to understand what happened as deeply as my not very scientifically trained mind can. Much, much praise is due, and I hope it will get the awards it deserves.
