Inspired by true events – or, as an opening title card explains, “based upon some fo' real, fo' real sh*t – BlacKkKlansman is a police procedural, a thriller, a comedy, a celebration of black identity, an indictment of white nationalism, and a rallying cry against more than a century's worth of media and public complacency, misrepresentation, and offense. Being a Spike Lee joint, the movie's stunning success on these and additional levels isn't necessary a surprise.
