It's nothing you haven't seen before, but that doesn't mean that it's a chore, reflecting on past wrongs and crimes, should be done all of the time, especially, as there are those who don't abhor; here we journey in the mire, the swamps that inflict pain and tire, to escape the evil clutches of the whip, the gun, dog judges, through a world that's cruel and dire, freedom's something you acquire, but you're more likely to win, a back of waves and rippled skin.
For me, the cinematography and the semi monochrome effect detracted from the whole. Some of the dialogue was a bit prosaic and the story was predictable; I needed to have the subtitles on to understand a lot of what was being said. I don't think it will go down as a landmark piece of filmmaking on the subject of slavery, to compare it to 12 Years a Slave or Antebellum or indeed Roots would give it credibility it doesn't deserve, but it does deserve some credit, and it does have a story to tell.
