The acting is impeccable, with seemingly little to no off the track actor highlights, which is desirable for a documentary-like work. Furthermore, the splitting of the time between the different sub stories works brilliantly to construct a close landscape for the viewer. Stunning visuals with masterful combination of the soundtrack and camera work to support the story and events rather than standing out by themselves. Nearly perfect pacing of the story, considering the large amount of events covered and how in-depth they were approached. Overall, a 10/10 piece of work, however, some of the liberties it takes in the fictionalization hinder it. While the introduction of a single scientist helping Legasov can be dismissed (as it is even shown in the end credits) as a way to dramatize the events, some encounters and lines are blatant anti-Russia propaganda. Seemingly, the usage of the English language can also be dismissed as a device to close to gap to the viewers. Those are not the main issues, as they are clearly indicated as to why they were done so. The inclusion of unnecessary remarks and unfundamented stereotypical characterizations, however, cuts some points at this masterpiece, that attempts to depict an event quite distant from the American culture, however, still idolizing it whenever possible. So, overall, 9/10.
