Interviews with “Firefly” staffers often include the question of “What story ideas were never produced?” As such, we know they were kicking around episodes about Kaylee having to go undercover as a Companion, and the Alliance accidentally producing a herd of mutant zombie cattle (yes, for real), but we’ll probably never see those stories.
Even in comparison to “Buffy” and “Angel” — which had already built up complex mythologies by the fall of 2002 — “Firefly” arrived as Joss Whedon’s most completely detailed and believable fictional universe. He imagined a 26th century where corporations and government are one and the same, American-looking people swear in Chinese (and have Asian-sounding last names, in the case of the Tam siblings, or dress in Asian fashions, as with Inara), and where prostitution is legal and respected — so long as the government can regulate it, of course.
As if to not overwhelm “Star Wars” fans who were also picking up the Blu-ray release of the films on Friday, the fourth season of “Star Wars: The Clone Wars” (7 p.m. Central Fridays on Cartoon Network) starts with a one-hour technical showcase that has very little story and character. It’s basically just a big underwater battle on Mon Calamari featuring four underwater races — the Mon Cala (a.k.a. Mon Cal in previous fiction) and Gungans on the side of the Republic, and the Quarren and a new shark-faced race on the side of the Separatists.
