Stephen Lovell describes Stalin's regime as "not an all-seeing executioner... but a slovenly, inhumane prison guard that leaves the inmates to fight a Hobbesian war of all against all".
Khrustalyov, My Car! is a highly stylised but incredibly compelling vision of what that might look and feels like. Tbh, you can almost smell it too.
If you want to hear a great discussion of it, I'd highly recommend listening to this episode of The Projection Booth and this episode of Flixwise: Canada.
