In an early chapter of DW Gibson’s oral history of modern gentrification, published back in 2015, one of the book’s “real life” characters asks him: Bushwick, what does that mean? Hipsterville? When hipsterville snakes its way to TV, it starts to feel familiar. For me, there was the one in the first season of “Girls,” which laid its claim to neighborhood authenticity in own overt terms: “Welcome to Bushwick a.k.a. The Crackcident.”
