What makes Metropolitans so hard to put down is the way Gittlitz weaves obsessive fan nostalgia, vivid retellings of legendary seasons (1969, 1986), and deep archival research into a compelling argument about the Mets as a "people's team"—a story as much about class and culture as baseball itself. The book wins readers over by pairing serious research with a partisan, high-energy voice and smart high/low cultural references that make the whole intellectual project feel urgent, alive, and wonderfully readable.
