The provocation begins with the title, a kind of reverse cultural appropriation: Nate Parker’s Sundance smash takes its name from a famous film released 101 years ago. Not just any film, but a cinematic titan of its era:The Birth of a Nation. D.W. Griffith’s mammoth Civil War film sold more tickets than any other movie, inspired a resurgence of the Ku Klux Klan, and caused enormous controversy as soon as it was released. The film is a synthesis of Griffith’s profound cinematic eloquence and some appallingly racist material, the latter having frequently dominated the conversation about Birth. Parker is reclaiming the title and adjusting film history. Fair enough, but if you’re going to reach that big, you’d better deliver.
