“Chernobyl,” the HBO mini-series that ends Monday in the U.S., isn’t easy to watch as someone who lived in the Soviet Union in 1986 and who has since visited the Chernobyl exclusion zone. But, like many of my compatriots, I’m watching it — and thinking it should have been made in Russia, Ukraine or Belarus, not by an American entertainment channel.

There are two reasons for this. One is authenticity — despite a valiant attempt at it, the series falls short. But the other, more important reason is that this kind of harsh sermon on the importance of listening to experts and running a government for the people, not for its own sake, should have come from one of the affected countries. Those countries, apparently, haven’t learned the lessons well enough to make a movie like this.

The authenticity part will probably be lost not just on Western viewers but also on the younger generation of post-Soviet ones, too. The producers tried hard to re-create the late Soviet material culture, even though it does look as though they found the objects at a flea market — they look 30 years the worse for wear.

Some lapses were probably too costly to avoid even when the filmmakers knew about them, like modern plastic windows in Soviet buildings. But there’s plenty more. Chernobyl is too far from Moscow to reach by helicopter, and in reality, the government commission sent there soon after the nuclear disaster took a plane to Kiev and then drove. Nor, of course, could Deputy Prime Minister Boris Shcherbina even imagine threatening to throw Valery Legasov, an esteemed member of the Soviet Academy of Sciences, off a helicopter — this was 1986, not 1936.

Legasov, one of the series’s central characters, did indeed hang himself two years after the Chernobyl disaster, having first taped his memories of it. But, as a top-flight scientist, he didn’t live in a dingy apartment with a characteristic deer rug on the wall: That would have been far below his station. Nor was a cat his only companion: As he sickened after multiple trips to the exploded nuclear power station, his wife and daughter took care of him.

I know for a fact from several reporting trips that Russian miners don’t drink vodka right at the mine, before they wash off the coal dust. And in the late ’80s, they didn’t require soldiers with assault rifles to keep them in check when a minister addressed them. For that matter, the soldiers in the series appear to hold their weapons U.S. style, butt to the armpit, not Soviet-style, across the chest.

Soviet people in 1986 didn’t go calling each other “comrade” except at Communist Party meetings. Ilya Repin’s dramatic painting of Ivan the Terrible realizing he’d just killed his son was never housed in the Kremlin. And some uniforms in the series are from the wrong period.
