The second paragraph of the review you posted is chilling enough and sets the tone:
"As Soviet citizens, they were survivors of a long experiment whose purpose was to reprogram the human soul. For almost 70 years, entire populations were schooled, cajoled and corralled behind moral fences. The ideological project required them to rewrite their history and redefine each of their lives. Through songs and festivals, leader cults, perverted science and the ubiquitous red flag, Soviet messages saturated everyone’s imagination, reaching into the most sceptical of minds. The system was so effective for so long that even after December 1991, when the Soviet Union collapsed, citizens wandered amid its wreckage like the recently bereft, haunted by the only set of values they had ever known."
Related: I just watched the Polish movie "Katyn" the past two nights. It's a about the Katyn massacre in WW II starting from the day the Germans invaded Poland to the immediate aftermath of WW II. It is a grim and somber picture of the Soviets controlling Poland post WW II and their coverup of their horrific war crime. It shows how the Soviets crushed the Poles and their desperate yearning (once again) for the return of freedom.
Wow! Thank you! I will be sure to watch it.
