Netflix: Documentary series ( M) An eight-episode, ravishingly filmed voyage through a crumbling American motor city now ranked among the most dangerous in the US, through the eyes of its understaffed police. “My first homicide was four days in,” 29-year-old officer Bridgette Balasko tells the camera, after apologising to a stitched-up robbery victim 27 hours after he called for help. Police numbers in Flint have been cut by two-thirds, the city apparently too broke to afford a fully functioning police department. The series opens as another body-blow – a poisoned water supply – lands on Flint, which has already been economically devastated by the pullout of General Motors. It ends after the toxic US presidential campaign of 2016. The filming is beautiful, surreally so at times. A teenage boy lies murdered in the snow. His mother’s anguish and the exhausted voices of attending officers underscore the heavy price of America’s civic poverty.
