“I just want to be a change agent, and politics is the way I can change people’s lives,” says 34-year-old Bakari Sellers in Emily L. Harrold’s fly-on-the-wall portrait of the idealistic attorney, politician, and CNN commentator. At 22 years of age, he ran for office as his district’s state representative and unexpectedly defeated his Republican opposition, but disillusionment soon set in. “I’m a Democrat in South Carolina, so my job is the definition of insanity, because I repeatedly do the same things over and over again, and don’t accomplish much,” he says of his tenure. And indeed one of his finest achievements occurred after he was out of office: while he was working as a social activist in the wake of the 2015 mass shootings at Emanuel A.M.E. Church in Charleston, he and others succeeded in finally convincing the state legislature to retire the Confederate flag from the statehouse grounds. Whatever you think of Sellers, who is immensely likable, if more openly emotional than the average guy—but hey, he’s hardly average—don’t miss this enlightening documentary, a primer on the risks and rewards of politics, and why it’s absolutely fundamental that all citizens engage in its discourse, on whatever level we can.
