I remember this happening in 1986 in real life but was a teenager at the time and didn't really get the scope of what happened. Seeing this through the prism of being and adult is so affecting and overwhelming..., from realizing how close the whole planet was to experiencing the effects of this catastrophe to what the people (individually and collectively) went through in the places within the region this actually happened in. Decisions and trauma we can only imagine. Every single position played a part from the fire fighters to the engineers, miners.., to the doctors and nurses along with all the regular people..., families and pets..., wild animals and the government types who always make everything worse -- literally every single life form in at least the immediate area was impacted. Your brain can get overwhelmed if you think about it too much. In as far as the performances, cinematography, sound etc it was fantastic and hauntingly beautiful. Definitely recommend.
