On a superficial level, this is a story that needs to be told. The racist violence in America is still endemic. But this is Hollywood revisionist history, as the FBI are NOT the good guys. Martin Luther King, Jr. received death threats on FBI stationary before he was murdered.
Not as bad as I thought it would be after reading Kael's, Rosenbaum's and Jim Emerson's pans. Parker knows how to load menace into wordless moments, and most of the time he shows both a patient gaze and a good sense of when to break from it. There are some cheap, garish moments that reminded me of his more flamboyant films, but they're relatively few. In terms of poltics, history and morality it's garbage.
