”Bringing together its own "Westphall Universe" collection of dynamic chapters, Televisual Shared Universes explores the intricate connections between spin-offs, transmedia narratives, and transfictionality. Through detailed and thorough analyses of key case studies (Star Trek, Doctor Who, DuckTales, Mighty Morphin' Power Rangers, Cheers, and many more!), the authors in this collection deftly explore what unifies—and splinters—the continuity of crossover. Highly recommended!
