The show really explores Chernobyl tragedy from all different points of view in a very realistic way.

How mistakes were hidden due to fear, the terrible consequences of hiding them, the sacrifice made by the people working at the site, How human lives seemed not to matter and How important it was, at the time of the Cold War, not to show any sign of weakness.

The final episode is real masterpiece with an excellent and very clear technical explanation of what happened in the reactor.
