When I heard that HBO and Sky UK were making a series called Chernobyl, knowing nothing about it, in my imagination I thought about a story set in an alternate universe sort of like Man in the High Castle which takes a fictional twist on history. Fortunately, the actual series is better than my idea for the premise. Real events can be more incredible than fiction. Chernobyl is a five part mini-series on the nuclear plant disaster that occurred in April 1986. Centered on the people dealing with the aftermath of the explosion, Chernobyl is a compelling and terrifying historical drama.
