Well then, why haven't you yet? You've had enough time to create this epic movie. You've made She's Got to Have It, School Daze, Do the Right Thing, Jungle Fever, Malcolm X, and a number of other movies. Where's the epic on slavery--that movie dedicated to our ancestors. The one person who you could have united with, for funding and networking, Tyler Perry, you have probably alienated. You could have honored our ancestors by learning to work with your peers and appreciating the value in their work or contribution, rather than always criticizing and appearing to be that "crab in the barrel."
Why don't you do what any intelligent person would do, reserve comment until after you see the movie? Oh, I forgot, you're not going to see it.
I say all this, and I continue to be one of your biggest fans, and I'm critical of Tyler Perry's movies as well. But what I don't like is playing the ancestor card. I take my ancestor veneration seriously. I have a shrine and make a pilgrimage annually to their grave sites, so I don't take lightly people using them as a scapegoat for their political, economic or egotistical platform! This sounds like a personal beef between you other director-producers you have sparred with in the past; some for valid reasons, others not. This performance you are putting on has little to do with our ancestors and may really be an effort to keep yourself relevant concerning movies about Black people.
I'm going to do the intelligent thing and see the movie, then give my impressions.
