As a riveting drama, it is hard to beat HBO's Chernobyl. The 4 episode miniseries deals with the worst nuclear accident in history, and all the consequences thereof. Thousands of people, such as nuclear workers, firefighters, military, miners, and scientists are in a race against time to contain the nuclear fallout that could affect a large area and contaminate millions of people. Some of these people lost their lives in the process.
As fantastic as Chernobyl is as a drama, it gets so many facts wrong both historically and scientifically that it has been the subject of much criticism. It repeatedly exaggerates the threat that the nuclear accident poses, going as far as to describe the plant as a nuclear bomb, claiming that it could lead to a 30 megaton explosion, and claiming that it could make half of Europe uninhabitable. According to people in the know, all of this is complete nonsense. The show further states that a large group of spectators on a bridge miles from the accident died from radiation poisoning, calling it the "death bridge." However, according to many sources, this is an urban legend.
Normally I would find these kinds of mistakes unforgivable, but Chernobyl also gets a great many facts right, not the least of which is the human suffering of a terrible nuclear accident. Some scenes might be too graphic for people. Chernobyl does not shy away from the more unpleasant aspects of this disaster.
Soviet politics are a major factor since the government seemed to be in denial. They were slow to realize that the accident is a serious problem.
Early on in the miniseries, many of the nuclear workers and scientists can't fathom how such an accident could happen. The show keeps us in suspense by saving the explanation for last. It was a combination of bad design and poor training leading to incompetent nuclear workers.
