May be RT is not the most reputed organ, but that particular article seemed written with an authentic motive:
"These elements of Soviet life may seem like the background to the central human stories, but in fact they dictated how each scene shown in Chernobyl unfolded in real life. And although occasionally the show hits upon the right note, perhaps when it sticks closest to a verbatim recreation, it does not seem to realize it. Most of the time, those involved act wrong on the wrong motivations, talk about the wrong things, and say them in the wrong order with an alien cadence that is more than just a different language."
"The most jarring scene is a Soviet minister bargaining with coal miners at gunpoint to persuade them to dig a tunnel under Chernobyl. Moscow mandarins did not negotiate with those 10 rungs below them – they sent down orders and didn’t need bullets to enforce them."
"Mazin’s party officials are more like sullen gangsters protecting their own patch – they bully, shout, laugh ostentatiously, and bang their fists on the table. Stellan Skarsgard’s senior cabinet minister threatens to throw Jared Harris’s renowned academic off a helicopter, then to shoot him, but the conversation is as implausible as it would be if it were shown between Vice President George H.W. Bush and physicist Richard Feynman, to pick two contemporaries."
