This show could easily be dismissed as another gangster/crime syndicate show upon first glance. And I would have done so if it weren't for the historical tie ins.
The show takes place in 1963 Harlem. The 60's in and of themselves were historically significant to America in general and Black Americans in particular. Harlem was a hotbed of activity during that time. So, while the main character is Bumpy Johnson (Forest Whitaker) we get to see people like Malcolm X, Cassius Clay, Adam Clayton Powell, and Elijah Muhammad. I'm not saying these people were all portrayed accurately, but they were significant historical figures and significant in the show.
The main theme is Bumpy Johnson's battle with the Italian Mafia. He wants Harlem for himself and a certain Vincent "Chin" Gigante (Vincent D'0nofrio) would like nothing more than to eliminate Bumpy Johnson altogether.
While that theme plays out with its ebbs and flows, we get to see other historical events play out (sometimes with actual footage). Cassius Clay fighting Doug Jones for a shot at the title, the march on Washington on August 28, 1963, the Kennedy assassination, and the Malcolm X/Nation of Islam saga. I'm sure much of it is dramatized and it may ruffle some feathers.
The show is intense and in your face. Pretty much all of the characters bring something to the show whether you like them or not. It's not a battle between good and evil or even evil and evil. All the characters are layered and complex even if the bad they do is heavier than the good they do. Watch it, allow yourself to be drawn in, and enjoy.
