Stray dogs, parking tickets, marriages, deaths, garbage collection, housing policy, climate change, civil rights: all these matters and more figure in this expansive look at the mundane and consequential business of city government in Boston. City Hall follows Democratic Mayor Marty Walsh, an affable Irish American with a spectacularly old-school accent, as he travels from conference rooms and church basements to Fenway Park and Faneuil Hall, regaling and exhorting citizens in the course of his executive duties. It also devotes significant screen time to the labor of low-profile municipal employees, and to community meetings where ordinary people hash out local issues, doing the basic work of democracy.
