When I started writing my most recent book, I Find Your Lack of Faith Disturbing: Star Wars and the Triumph of Geek Culture, I wanted to make an argument about aesthetics. Namely, I wanted to argue that when it comes to art, geeks tend to like works of realist fantasy, which puts the lie to the widespread belief that realism and fantasy are opposites. (They’re not: realism is a mode, or way of making art, while fantasy is a genre; any genre can be done in any mode.)
As I worked on the book, however, I realized that people were just as interested, if not more interested, in the history of geek culture. Whenever I told people what I was doing, they said that they hoped the book would explain why geeky stuff is everywhere these days—why it’s taken over the culture. Why are all the movies at the Cineplex superhero movies? Why is everyone talking about Game of Thrones? Why is it now considered OK, or mostly OK, for adults to read Harry Potter novels and comic books? So I knew I needed to write about that, too.
As it turned out, this wasn’t a problem, because the two topics are intimately intertwined. Indeed, you can’t understand the history of geek culture without also grasping its aesthetics.
