Here is your problem, you want a slave film in which the end result makes YOU feel good, where slave took up arms and overcame without aid of any white man. Newsflash, NONE EXIST in this United States of America. Every slave revolt, or attempted slave result ended up UNSUCCESSFUL and achieved nothing in the end. Django Unchained is a revenge FANTASY and not put on a pedestal as an accurate historical account. It was purposely made as a revenge fantasy to give retribution and honor to slaves that had endured slavery, or fought and died in the name of slavery. But it is not the reality of back then and surely not today!
You want to bring up Nat Turner, which indeed was the biggest slave revort that ever happened on American soil, but you DO know how that ended up. You do understand that it ended up being unsuccessful and made Congress to pass harsher and more cruel laws on slavery. It made matters worse. It's only been romanticized now because it was about a slave that tried to stand up against the slaver, but in order to appreciate that in its fullness you HAVE to understand the cruel realities our people was forced to suffer and contined on suffering well beyond the actual end of slavery.
You asking for a film that makes you FEEL good because you cannot accept the actual REALITY of how it was. 12 Years a Slave was REALITY, unapologetic. That was the life. You saw someone who was ready to fight for his, you see how passive slaves were. That how it WAS. You saw how different an educated free man is from a born into slavery individual and you journeyed through the eyes of someone who thought he was free transform himself ot acceptance of being no different from those of a slave. This is the TRUTH.
Yes, there WERE slave revolts, but none of them were successful. The only successful American slave revolt we had was ALREADY put on film and that's "Armistad" and that was merely on a slave ship, and still had to endure the BS like the rest of the Africans.
