It’s hard to explain what “Show Me a Hero” is about. The HBO miniseries debuting this Sunday is technically about the controversy over a federal affordable housing policy being enacted in Yonkers, New York, in the late 1980s. It is specifically about Yonkers Mayor Nick Wasicsko, the youngest mayor in America, who—through a mix of opportunism and luck—became the figurehead of that debate. It is more broadly about American race relations, and how the life of a city hinges completely on its citizens’ willingness to respect and acknowledge their neighbors. It is about the relationship people have to their homes; the investment people have in their communities.
