Billy Corben's "Dawg Fight" looks at DIY pugilism in West Perrine, Florida, one-time home of Kimbo Slice aka "King of the Web Brawlers," in 2008. A viral sensation from videos of mutual combat street fights, Slice made it out of the ghetto into a stable mixed martial arts career. For the most part, "Dawg Fight" is the story of those who don't. Perrine, a predominantly black neighborhood (with whites in East Perrine, having developed in segregated fashion) is plagued by poverty, unemployment, and high crime rates, with a sizable portion of its males ending up incarcerated or not even making it past 30. Corben is less interested in the voyeuristic miserablism this would suggest than in communal bonds built around potential escape, here offered by former Kimbo-apprentice-turned-stentorian-backyard-organizer Dhafir "Dada 5000" Harris and his family. Dada refers to Perrine as "the dark side" of Miami no one knows about, with hopes of changing that for the better.
