On her Twitter, the British screenwriter Karla Marie Sweet critiqued show because there are no black actors in Chernobyl. When followers noticed that there were no black people in Soviet Ukraine, she said, that actors don’t speak with a Ukrainian accent too, so if there is no absolute realism, why not to add colored actors in the cast?
«Chernobyl» creators tried to show the ineptitude of the soviet authority and its atmosphere of total lie at first. However, regular citizens who cleaned up the explosion effects, are described as heroes. So there is no surprise that the miniseries was criticized by Russian officials.
