Katyn

An excellent Polish film that shows quite clearly one of the most horrible hidden events of the WWII (only confessed 50 years later by Gorbachev). One of the massive and bloody crimes made by Stalin, who ordered to kill coolly 22,000 people (the higher Polish officers and most of their elite people of the country) to erase the possibility that Poland could "reborn" after Stalin and Hitler dealt out Poland like a pie. Very recommendable.

My score: 9 (out of 10)
