Chernobyl’s writer, Craig Mazin and director Johan Renck were very upfront in stating that this production was not a documentary but a fictionalized version of events. In other words, Chernoybl is about as accurate as other historical dramas such as the film adaptations of The Right Stuff, All the President’s Men, Hidden Figures, Chariots of Fire, Selma and Moneyball. These works don’t tell the LITERAL truth of their stories but the ESSENTIAL truth of what happened.
Screenwriter Craig Mazin said that "The lesson of Chernobyl isn't that modern nuclear power is dangerous. The lesson is that lying, arrogance, and suppression of criticism are dangerous".
In the middle of watching Chernobyl, I wrote the following post on my Facebook wall:
After seeing three of Chernobyl's five episodes, I have no doubt WHATSOEVER that it is one of the most excruciating, shocking, sorrowful dramas in the history of television. It is brilliantly acted through an astonishing ensemble and I have yet to detect a false note in it's script or direction.
People, I've seen a TON of television in my life and I say this from the heart, you may never see a finer drama in your lifetime than HBO's Chernobyl. SEE IT!
