I like the series, but it is somewhat dramatized and technically incorrect in places; some people may understand the focus on drama as a statement against nuclear energy, which would be regrettable. I think the show says close to nothing new about the technology and its risks, the bad effects of radioactivity and bad design of RBMK are well known to people who study nuclear physics and medicine. The accident was terrible, but in terms of lives nothing like a big tsunami or largest chemical disasters. But it shows how bad our governments are; the show rightly exposes how the totalitarian political system was instrumental in the disaster and botched reaction to it: and things such as "state can admit no error or wrongdoing", "appearance of state success is more important than people lives" and "vital technological information should be classified as top secret even if it can save lives", all sound too familiar even today.
