Amazing that it's been 15 years. Of all the Fox blunders, this is probably their worst.
Imagine, they could have had the equivalent of Star Wars or the Star Trek Universes (ok, galaxies, but still). If not that big, Stargate, then. (You know, with only 4 or is it 5? spinoffs) Can you think of all the possibilities for spinoffs and other in-universe movies?
Telling the story of the War. Telling the stories of the migration from Earth That Was. Pull a switch and get a view from the Alliance. "Firefly, the Next Generation"
Instead, they killed the goose that could have laid the golden eggs.
What's particularly galling is no one has even tried. They have that much of an audience that would at least give such a thing a chance and for 15 years, they've decided to go with a decade and a half of crap.
Sarah Connor Chronicles? Dollhouse? Gotham? This gorram "Orville" show?
Great vision Fox. How do you stay in business?
