The first narrative feature film by documentarian Crystal Moselle (The Wolf Pack, 2015) opens with a black screen and the sounds of the city: A train rattles and screeches by, people shout, children play, and a skateboard hits the pavement. Even before we see the film’s protagonist perform her first onscreen skateboard trick, the feeling is already somehow both electric and familiar, much like the story that follows. The film tracks its young heroine as she joins an all-girl skate crew in New York City. (In a move that blurs the line between documentary and narrative film, the fictional crew is made up of members of the real-life crew known as Skate Kitchen.) All the usual elements of outsider stories, sports movies, and teen dramas abound: A young upstart joins a team of mavericks, tests her skills against those of her teammates and those of her opponents, and clashes with members of both as she grows and finds out more about herself. But this film invests the familiar sports-movie and coming-of-age-drama tropes with a raw energy, honesty, frank physicality, and genuine feeling that elevate it from a mere genre film into something precise and visceral.
