Anyone watched the HBO series Chernobyl? I'm pretty impressed. I was a teenager during that time and couldn't believe how realistic the Soviet milieu in the movie was. The only thing missing was the Russian language. The actors, too, seemed pretty realistic and didn't give off many U.S. vibes
Of course it's not a documentary, so one cannot expect that the events would be depicted with 100% accuracy. But they're close enough to the real thing, for a TV series.
