First, kudos to the writers of this miniseries. They've taken a big event and found a way to tell a story of human corruption and sacrifice with a core group of central characters. The production values are great - you really feel like you're looking back at the Soviet Union in the 80s.

However, the description of how a nuclear plant works is sadly lacking. Most of it is stuffed into a long recitation in the last episode ... along with an explanation of the failure. Good luck in understanding it. However, a few minutes on YouTube can answer those questions far better than show did.

But that aside, this is still worthwhile viewing. Perhaps no where else will you get an immediate sense of the scope and scale of the event than in this show.
