First of all, I have to mention that I am definitely not a series fan. Can't stand the fact that in order to get a whole picture I have to watch 6 seasons with 20 episodes each.

So the first thing I enjoyed was a great format - mini-series (5 hours long). Longer than a normal movie and way shorter than series. Gives you just enough information to process and actually enjoy the content. Worked well for Chernobyl's subject because if it would be shorter then the audience wouldn't have a whole picture. And if it would be longer it would be boring.

A rich mix of feelings throughout the whole series length. I felt depressed, disgusted, sorrow, sedated and anxious. Series ending left me with a mixed feeling for quite a while.

Deep compassion. I decided to separate this feeling from all others because most of the movies or series on a similar subject do not provoke the same feeling inside me. However, this one does.

Memorable characters. Great casting job since every person fits in the picture harmoniously. Even people in masks are different from each other in a good way.

Good background knowledge of the subject. The fact that I was interested in the history of the Chernobyl events made series more entertaining. Have to give credit for accuracy on most of scenes and details.

To conclude I would say that even if you aren't into series in general - this particular one is definitely worth a try.
