The 45th film from Frederick Wiseman, “City Hall” immerses audiences in the municipality of his hometown of Boston to illustrate a government taking care of its diverse citizens. Through his filmmaking, audiences come to realize how city government touches upon almost every aspect of their lives, acknowledging how necessary services like sanitation, veterans affairs, elder support, parks, licensing bureaus, recordkeeping, as well as a myriad of other activities that support the citizenry, are often taken for granted.
