I think most would embrace a feature-length documentary on the late Dwayne McDuffie and the institution he created Milestone Media/Comics, a coalition of African American artists and writers and comic book company owned by African Americans, striving to positively address the lack of minorities in American comics, fighting for recognition and acclaim in an industry dominated by whites, both the characters within the comics, as well as the people who create, market and sell them.
The closest we'll get to it is this unfinished short documentary by scholar and University of Georgia Professor, Jonathan Gayles (you might recall his feature documentary Shaft or Sidney Poitier: Black Masculinity In Comic Books, which we covered quite a bit on S&A last year, including an interview with Gayles, which you can read HERE; the film is now called White Scripts And Black Supermen – Black Masculinities In American Comic Books, and it's played many film festivals).
