When Joss Whedon's television show Firefly (2002-2003) was cancelled, devoted fans cried foul and demanded more--which led to the 2005 feature film Serenity. Both the series and the film were celebrated for their melding of science fiction and western iconography, dystopian settings, underdog storylines, and clever fast-paced dialogue. Firefly has garnered a great deal of scholarly attention--less so, Serenity. This collection of new essays, the first focusing exclusively on the film, examines its depictions of race, ableism, social engineering and systems of power, and its status as a crime film, among other topics.
