2.5 hours of Boring
First, the director (Tate Taylor) has been telling all of the tabloid t.v. shows that he deliberately revised and underplayed James Brown's violence and played up the white racism. In other words, this is really not a biopic, but an imagining of what James Brown might be like if a director wanted to use a famous black entertainer to teach that white people were all awful and must pay reparations to blacks for anything that happened to any black in the past by paying off all blacks. Every white person in the film is a vile devilish racist, except for James Brown's manager who is a stereotypical Jew who loves loves loves money above all else. The film also was written to make James Brown a business and financial genius, when in real life he was the opposite (he was disorganized, he owed the feds millions, and was constantly in debt to everyone). So this film about James Brown is really about a different person the director named James Brown to get you in the theatre.
Second, the film makes thew point that James' mother abandoning him and his father sending him to his aunt's brothel to be raised is white society's fault, not his parent's. And his wife-beating (as I said, "played down") is also the white person's fault.
So the film is for liberal white people needing their "kick me" fix and blacks who embrace being victims of their own lives. Predictably, the largely black audience in my theatre clapped at the end. Much I suppose they clapped when OJ was found not guilty of Nicole Brown's and Goldman's murders.
Third, it's a "lecture" movie. You are lectured that James Brown was entitled to be a violent jerk and criminal because of whites.
