I was hesitant to watch because I have a nuclear engineering degree, have studied the event personally and in class, and figured I'd get angry at how incorrect everything was. I had nothing to do tonight and my coworkers had been adamant I watch so I figured why not.
After binge watching 4 episodes all I can say is wow. They got literally every aspect right. The reactor physics, the radiation effects, the timeline, the cleanup efforts, and the corruption of the Soviets. They literally got it all right. I can't wait for the last episode because it looks like the trial and events of that day are going to be shown via flashback. Obviously its' a topic I'm heavily interested in, but this is probably my favorite show ever.
