What they make clear is that Poland was never liberated. World War 2 never really ended for them, until 1990, or thereabouts. One fascistic regime was replaced by another, and as I have often said, I consider Communism vastly more evil than Nazism. Nazis just wanted your body. The Communists want your soul.
And you UNDERSTAND, watching this, that the whole enterprise is like a nation being run by one of those sociopaths you have met at one time or another, who does whatever they want, then lies about it, convincingly, and never shows the slightest sign of even caring what the truth is.
I think this should be required viewing for high school age kids. It balances the overabundance of anti-Nazi movies–not that there is not a lot to hate there–relative to the much larger, much longer term, and much nastier crimes of Communists the world over.
