Pious but not sanctimonious, Kevin Macdonald’s documentary on Jamaican-reggae-god Bob Marley hits all the high points and some low ones. It is rich in concert and interview material and maintains a sexy pulse of Caribbean affirmation, thanks to the nectar of goodwill in most of Marley’s songs. And in him. The charisma lingers lavishly. 2012.
