Anyone who has studied the Soviet Union knows they lied and hid many things from the people of their own country, and Chernobyl was the same treatment. However in this mini-series the writers decided to completely make up a character for the movie, and it happens to be a "concerned scientist" Ulana Khomyuk that never existed in real life. This was done to supposedly represent the "scientific community" of the Soviet Union. However having a faked character also turns this into a fake drama, when there was no need to make up anything. The poor reactor design, the sloppy operators, the Soviet bureaucracy that covers up everything to hide the truth, the slow response and lies was more than enough to carry this by itself. Instead they manufactured a hero where none existed. Sort of what like the Soviet Union would do. The mini-series does have an authentic look to it, with good dialog and corrupt government officials, military people, and judges. Just try not to believe all of it.
