The cost of lies is Chernobyl. This is just too amazing, deeply shaking and brilliantly acted series. The show keeps you gripped to the story so well that you never realize when the episode is over, you are not only eager to know what happened next but also terrified to know the truth.
The more you think that it's a true story the more shaken you are to the core. Goosebumps are you constant companion throughout the show. Also, If you deeply feel in pain, anguish, perplexed and astonished then these are just a few emotions that will remain with you even after the show ends.
All I can say is that if the truth comes with a cost then the lies comes with greater cost.
Do watch it, if nothing else, you will get to see the extraordinary bravery shown by some people even in the midst of the greatest nuclear disaster in the history of human history whose footsteps will still be heard even after a thousand year.
