Do you see Lee's films as being more for black people or white people?
I have the strong impression Lee's recent films including this one have not been big hits with black people, although I could be wrong.
I'm white and a film buff. I'm a fan of Lee's although some of his films have been better than others and a few I did not see. I thought Chi-Raq was great. I saw it at home, so can't comment on the audience. But I think if it had been a bigger hit with black people it would have played for longer in theaters here (New York) as our population is 25 percent black. Not to mention Lee is a New Yorker.
It was a risk to take an ancient Greek play and turn it into a musical/rap about gang violence. Uneducated people might have been confused by this. In addition, the movie features young or young-ish black actors such as Nick Cannon, but although it has some rap numbers it also uses old soul music that many people under the age of 40 have no familiarity with. I seriously doubt very many black people under the age of 40 went to see this film unless they are film students.
There are a lot of racist white people who will see no film with a black cast, but there's also a strong percentage of white people around my age (middle age) who grew up in the heyday of the "auteur" filmmaker and we see Lee as one of those people.
In short I think this film probably appeals mostly to educated black people over 40 and educated white people over 45 who remember Lee's films from their young adulthood or who are film buffs and are aware of his history as a risk-taking black filmmaker. No wonder the movie didn't do that great at the box office.
