Lots of moments of people looking into the camera and going "how could communism do this?" which is cringe, but otherwise it's a fantastic story of human drama and how bad shit can get. Funny, I read this morning that Gorby is now dead, weird timing.
Aside from some woeful science and frequent hyping up the drama of "Guy goes into radiation, he doooooommmed, radiation is a mystical death curse that you can get from touching someone a week later" (the guy lived in RL, no you can't get radiation from someone with radiation sickness who's been, say, given a bath) it has a lot of good points.
