This whole situation is silly. No one is obligated to go spend their money on a movie no matter the content nor the creator of said content. There are more than one means of gaining access to the information about our ancestor Nat Turner, one means of which I am partial to is via books. This blaming people for not spending their money on a movie just because we like the subject matter is childish and should be below us.
Then you don't get to complain when our stories are no longer told from our point of view. It's as simple as that
