Two almost forgotten mass genocides are now made into movies.
I would suggest viewing both as a reminder of what happened and should not be repeated.
Bitter Harvest aka the Holomodor is set in early 1930s Soviet Union. Stalin manipulated a manmade famine in the Ukraine.

About 7 million Ukrainians and another 2 million other ethnics were purposely starved to death to destroy private farming and initiate collective farms. The communists thought this would generate more wheat and funds to build communist. It didn't, of course, but government did gain control of agriculture. This was the first time the NY Times was a genocide denier. They sent their stooge, Walter Duranty, in to prove the rumors of genocide were false. He even received a Pulitzer award for his fake news. Mao used the same strategy to gain control of agriculture in China. The North Vietnamese did the same in South Vietnam.
The second movie is The Promise. http://thepromise.movie/
The Promise takes place from 1915 to 1917 in the Ottoman Empire. About 1.5 million Armenians were systematically murdered by the Turks. Armenians were indigenous Christians within the Empire and some of the their best soldiers. The Muslim leadership feared the Armenians would side with the Russians during WWI. The successor government to the Ottoman Empire long denied the genocide. As the new secular government was not responsible for the actions of the old empire, they should have simply acknowledged the genocide and that they were not responsible for it. Unfortunately, the new leader Erdogan has destroyed the old secular government and is dead set on reestablishing the caliphate of the Ottomans. Just as the Persians are set on reestablishing the Persian Empire. Both are willing to die to the last Arab to do so.
BTW, the second time the NY Times denied genocide was the Holocaust. The Polish government-in-exile gave evidence. The Times refused to acknowledge the Holocaust until the Allies practically marched into the death camps' gates.
