One thing I discussed recently with my parents regarding Chernobyl (outside of them freaking out about how accurate the scenery and costumes were - since they were around my age when the real accident occurred their memory of it is still good) is how respectfully the series portrayed the sacrifices and suffering of those involved.

We see all those people that suffer due to effects of the disaster - the firefighters, liquidators, plant operators and so on - and yet it never descends to the level of showing something only for the shock value. 

It would have been incredibly easy, for example, to show how Akimov looked or spend more time on the sequence of Lyudmila giving birth or to show far worse details of Vasylis demise or more graphic images of the “cleanup” in Episode 4 (especially since a lot of it was described in great detail in Voices of Chernobyl), but the show never strays into that realm. Instead, it relies on showing the viewer enough for them to understand the gravity of the situation and the cost of the disaster on human lives while at the same time staying a little bit back, just to give a perspective but to preserve the dignity of those who had to endure.

And I somehow think it might be one of the most important things the show carries through.
