During the American Civil War, a mixed race group of army deserters and escapee/freed slaves thought "Fuck all this bollocks, let's set up our own place far away from the politics of wealth and race that is getting people killed in huge numbers."
150 years later, some people still consider Newton Knight, a white man who played a formative role in this separatist idea based on freedom and fairness, to be a traitor to his country.
So the lesson from this film, you could say, is that no matter how hard you try and make the world a better place, there's always gonna be stupid cunts.
This film was a box office bomb. Political perspectives aside, I'm surprised. It's set in an interesting period, the story told is a fascinating one, and the battle scenes are both horrific and greatly exciting.
Worth a watch.
