If you've studied WWI a bit, you'll know that while the Ottoman Empire was crumbling a group called the "Young Turks" decided that Turkey would rid itself of everyone not Turkish. If you agreed to convert to Islam, you might be spared. So much happened and on such a large scale that you could easily do a mini-series, so the film is a little long and some conflation of things was necessary. It is not unrealistic that Armenians could escape from one situation and then simply find themselves driven from one horror to another. Yes, some Armenians were worked to death by the military, some escaped and tried to hide out, and yes, a few thousand were rescued off of Musa Dagh (a mountain), close to the Mediterranean Sea. Bottom line, this film manages to convey the horror of being hated simply for who you are and targeted for extermination. Oscar Isaac is just phenomenal, and the rest of the cast is very good. The incredible atrocities are played down, fact is if they showed the viewer even 15% of what happened in detail, it would make it hard to attract viewers. The genocide against Armenians, Assyrians, Greeks and other non-Turks is well documented and supported by historians in general. It's a historical fact. The only historians who try to downplay or deny there was a genocide are usually being supported financially by the Turkish government. Those who did not die were largely women/girls who were handed off to Turkish families. I would guess that a large portion of Turks do in fact have an Armenian grandmother or great grandmother. After years of the Turkish government threatening the diaspora and attacking anyone who insisted that this happened, it is extremely heartening that this film has been made.
