How do you take a story of Chikatillo and make it somehow the government's fault?
Why take the serial crimes happening in 1978-1990s and place these in 1960s?
A get all about the artistic licence. And I'm no fan of USSR as well. But I'm no fan of blatant misrepresentation of widely-known facts.
You don't really make it seem like people can be forced to make allegations against their neighbours. When there was a slew of denunciations during the Stalin's terror yet, oh wonder!, there were people who did not do any. Imagine that? What, did they live in a different country from the ones who did? The bottomline is that it is always people who make the ultimate choices.
I think this will be a DNF. Will give it a try sometime later. Maybe I'll get it better in a more appropriate mood.
