Thankfully this show did not go down the anti-nuclear route and sensationalized the whole event, it pretty much stuck to the facts as we know it. Ok there was some dramatic license taken with the court case and legasovs final denouement, and of course the creation of the fictional female scientist, but in large it was very accurate. Particularly impressive was the reconstruction of the liquidators on the roof, watch the real videos and you will see how accurate they tried to portray the events. But perhaps the most impressive part of the show was how they managed to explain the accident, it's not a simple thing and TV (and certainly movies) often grossly simplify complex events, but they took it on brilliantly and despite lots of books on the subject this is probably the best lay mans explanation there is.
