The Soviet Union of the 1980s is becoming a sort of cinematic sub-genre of its very own.
This excellent Russian sci-fi horror might be open to complaints of Ridley Scott derivative-ness, but largely heads them off by virtue of being set within a highly-stylised version of that extraordinary period.
I say stylised, because here the deliberate drabness occasionally occasionally comes across as rather attractive.
And the USSR of this period in my own memories is anything but stylish. There were some prime colours around, just in all the wrong places.
