It is a good explanation of the unfortunate and sad accident in Chernobyl. I am not sure how much of it is exact but if it is completely based on facts it is very informative. However I really don't get this much hype for it. Am I missing something? Maybe I am but more than what I have said I can't find anything else in which it deserves this much compliment. A 9.7/10 seems certainty an overrated score to me.

Do I recommend it? Yes. It is informative and has been well made. But there are many other shows and movies providing this quality and higher. So it is only a higher than average one no more.
