This was written by Armando Iannucci who is a well known satirist in the UK. He did Veep and a bunch of other stuff that savagely shows the absurdity of our political classes and powerful people being shits. I think his comedy is pretty awesome really as tedns to frame situations and characters in a ridiculous manner rather than overly exaggerating them.
Heard a lot of good stuff about The Death of Stalin. Will deffo watch this, although I don't expect to lol so much as cringe a bit and appreciate the insanity and farce of it all.
