I'm surprisingly bitter about this franchise. All I can really think about this spin off is...didn't they do this before, in terms of promising to explore this universe more with a female lead as part of the hook? What makes this time different?
The first spin off failed to illuminate anything, imho, and they aren't even bothering to tell full stories on the mothership (details are "the weeds," character conclusions will be told in tv movies). Plus, isn't the premise kind of Judith's story? Why not just use her, instead of focusing on yet another villian our heroes were woefully unprepared to handle? Or, y'know, do both things, on the show you already have.
I'll follow spoilers, cause I get addicted to soaps and this is no different, but people will have to rave about it to get me to watch. A "twist" like killing off half the cast midway through the season, or bringing on Maggie's kid, won't do it, though I feel like both of those things are likely.
