Death of Stalin is a straight masterpiece if you ask me.
It takes a lot more that one run to take in all the subtleties in the dialogue. I personally have watched it at least 5 times and enjoyed the heck out of each and every run.

I remember when it came out and reached Russia, the pundits on Kremlin TV had such a hissy fit it was like watching vampires writhe at the sight of garlic LOL

A beautiful beautiful piece of cinema. Close to real time events too but with understandable omissions.
