This book explores the concept that, as participation in traditional religion declines, the complex and fantastical worlds of speculative television have become the place where theological questions and issues are negotiated, understood, and formed. From bodies, robots, and souls to purgatories and post-apocalyptic scenarios and new forms of digital scripture, the shows examined – from Buffy the Vampire Slayer to Westworld – invite their viewers and fans to engage with and imagine concepts traditionally reserved for religious spaces. Informed by recent trends in both fan studies and religious studies, and with an emphasis on practice as well as belief, the thematically focused narrative posits that it is through the intersections of these shows that we find the reframing and rethinking of religious ideas. This truly interdisciplinary work will resonate with scholars and upper-level students in the areas of religion, television studies, popular culture, fan studies, media studies, and philosophy.
