9.8/10. THE greatest mini/limited series I have ever watched. From beginning to end this season just enthralled me and got me invested in this horrific tragedy. Before this series, I knew of the nuclear meltdown but had no idea it was this bad. The cinematography was next level. The way the producers used cinematography to convey aspects of the story was beautiful. The characters/acting was perfect. Jared Harris as Legasov and Stellan Skarsgård as Boris were both perfect castings. Stellan Skarsgård's performances in both Andor and this series prove how much of a goat he is. This also had so many Game of Thrones actors sprinkled all around. Overall a near-perfect show with minimal flaws. S Tier.
