They grew up together in Rockford, Ill., three boys united by their love of skateboarding. At a certain point — around middle school, it seems — one of them, Bing Liu, began videotaping their exploits.
A pleasure of “Minding the Gap,” his astonishing debut feature, is to observe how skating and filmmaking flow together. As the young men get stronger, bolder and more dexterous, Mr. Liu’s camera skills keep pace, and he captures the sense of risk, freedom and creativity that makes their pastime more than just a hobby.
It’s not only the glue that binds them to one another through tough times but also a source of identity and meaning, a way of life and a life saver. “Minding the Gap” is more than a celebration of skateboarding as a sport and a subculture. With infinite sensitivity, Mr. Liu delves into some of the most painful and intimate details of his friends’ lives and his own, and then layers his observations into a rich, devastating essay on race, class and manhood in 21st-century America.
