At the end of history, nothing ever really ends. Though characterized, on one hand, by sociopolitical and economic stasis, stagnation, and decline, twenty-first century American culture has also been marked by the constant ebb and flow of preexisting artifacts and styles, so that when one fades out of fashion it is always replaced by another reiteration. Change, on the cultural level, has accelerated at an unprecedented rate, and old things are constantly returning anew. The present, in other words, promotes the feeling that nothing is changing and, simultaneously, everything is. In the midst of this paradoxical sense of constant flux and grinding stagnation, underwritten by the notion that there is no alternative to the malaise of the present, the nostalgic past emerges as the only viable refuge. The Reflective Age investigates how nostalgic American media of the 2010s and early 2020s reflects––and contributes to––these conditions, showing how the films, TV shows, music, and literature of the period illustrate a radical shift in both the role that nostalgia plays in the American cultural and political landscape as well as in nostalgia itself.
