I saw this film about a month ago. I thought it was an accurate description of the life of the higher ups in Soviet times. Yes, it was funny. But scary.
The best part (I thought) was the meeting of the officials after Stalin’s death. It was interesting to see how each was trying to engineer the meeting in such a way as to make it political incorrect for others to muster some opposition to an idea. This was fantastic writing and acting.
I remember a few instances like that in days in the back rooms of a Canadian political party. Fortunately the stakes weren’t quite so high.
