Book excerpt: As evidenced by the recent proliferation of fan conventions, television show boxed sets, and collectible character figurines, cult TV shows have arguably become the most vital and interesting programming on television. The once-marginal genre manifests itself in a remarkable variety of programs, from the suburban mob drama The Sopranos to the beloved occult fantasy Buffy the Vampire Slayer. The Cult TV Book is a guide to this phenomenon, complete with lively and diverse analyses of the work that goes into conceiving and marketing a cult series, as well as numerous investigations that explore the unique cult appeal of individual programs. Leading scholars, journalists, and writers consider the many aspects of a show — both script-based and visual — that attract the kind of uncompromisingly loyal fan bases that we know as “Trekkies,” for example, or, more recently, “Losties.” The Cult TV Book sheds light on the heretofore under-examined science of addictive TV programming, pinpointing the complex arcs and intentionally inadequate explanations that keep viewers coming back for more. The contributors cover every corner of the cult map, all the while trying to define the elusive genre, to understand the cult TV obsession from the outside in.
