True. All of the real lead characters mentioned in this thread that are community/family leaders but aren't "fatally flawed" are based on real people. The Pursuit of Happyness was based on the true story of a homeless man living in the Tenderloin (San Francisco).
It really says a lot when you think about it... Hollywood goes through a lot of trouble to undermine any strong black male character and takes every opportunity to portray us being unfit/undeserving/incompetent/evil when we have any kind of power that isn't given out or controlled by white people.
Furious Styles might really be the only strong black male lead character who was community/family focused that was intentionally written that way by the screenwriters of a major motion picture
I know that he wasn't the lead but he was a main character for sure.
