First off, nobody normal spends 25 days with dozens of posts a day criticizing a TV show. Second, from the Moscow Times:

Komsomolskaya Pravda (KP), Russia’s most popular newspaper, raised suspicions that competitors of state-atomic center Rosatom were using the series to tarnish this country’s image as a nuclear power.

Argumenty i Fakty, a newspaper popular among the elderly, dismissed the show as “a caricature and not the truth.”

“The only things missing are the bears and accordions!” quipped Stanislav Natanzon, lead anchor of Rossia 24, one of the country’s main news channels. He pointed to shots showing modern storm windows on a building in Pripyat — that are only visible if you greatly enlarge the image — as evidence of shoddy filmmaking. However, critics of the series found fault with more than just minor details.

“Still, an attempt will be made to put an entirely different spin on those events. Russia’s NTV channel has already announced that it is shooting its own “Chernobyl” series based on the premise that the CIA sent an agent to the Chernobyl zone to carry out acts of sabotage.”

So what’s that about nobody caring? Hmm. Russian troll fail.
