I'm a few years late in checking this documentary out, but Next - A Primer on Urban Painting by Pablo Aravena is a great homage to modern street artists. It tells of graffiti going beyond the streets into galleries, and what's more interesting--street culture in a global context--document of visual expression, politics and history at a primal level. One segment which really stood out was an interview with a Brazilian graffiti artist and his perception that unauthorized graffiti in Brazil wasn't as persecuted as it is in the US mainly because of the social climate--how the Brazilian authorities have larger crimes to attend to. Art was a source of escape from their daily lives.
