When HBO released "Chernobyl (2019)" everyone went nuts on those series and all in all Chernobyl disaster is such a famous disasted in a world, but seems like there have been other disasters that we never heard and those disasters aren't any less important in my opinion and this series are the proof. To be honest, I watched both Chernobyl (2019) and these series and I liked this one much more than Chernobyl (2019). I think Chernobyl (2019) is overhyped just because it's HBO series. You know people are sheep worshipping and following brands, but I can tell you that Netflix did better job with these series. Production, acting and performance is top notch. Heck, even character development is better here than in Chernobyl (2019). Overall, I was very pleased with these series. I give it solid 10/10.

Top notch casting! The series itself shows the infamous gas tragedy, but the part which has been less known to the common people ie., the railway men whose courage saved large number of people.
Good choice to make it a mini series and show only the necessary, absolutely felt every moment of that tragic night at Bhopal.
