Last year, some of the best documentaries, “Won’t You Be My Neighbor?”, “Bisbee ’17”, “RBG”, and “Minding the Gap”, made their Chicago debut at the DOC10 film festival, which means you should be looking closely at this year’s lineup. Presented by Chicago Media Project, the festival returns to the Davis Theater this weekend in the Lincoln Square neighborhood. That’s right, another weekend in Chicago means another film festival. The film’s selected are the best documentaries from the festival circuit within the last six months. All of the four films I was privy to see premiered at the Sundance Film Festival this past January. It’ll be interesting to see which of this year’s DOC10 films take off once they get their inevitable release.
