Comprehensive it isn't.
American indian, anyone?
This views like an 80's public school history lesson. Lincolns north were the good guys!! Out to destroy the evil in our lands.. yeah, right.
Apart from a couple random statements "he went out west to fight indians".. "the only good indian is a dead indian" etc.. there is not one mention of the American indian in this entire series.
The fact is, the very same people responsible for (the both locally and internationally widely opposed convenient last ditch effort to save the political cause) "freeing" of the African slave (as if), including and especially Lincoln himself, are also responsible for beginning the ongoing systematic extermination of the native people, purely out of ego/greed and of course monetary gain.
While visually stunning, I am disgusted with the message put forth in this series. Next.
