Dystopian and post-apocalyptic movies from 1968 to 2021 usually conclude with optimism, with a window into what is possible in the face of social dysfunction - and worse. The infrastructure that peeks through at the edges of the frame surfaces some of the concrete ways in which dystopian and post-apocalyptic survivors have made do with their damaged and destroyed worlds.

We can look to dystopian and post-apocalyptic movies for a sense of where we might begin.
