But I also think she had the pull to say "this stays" regarding Lucas' outline. IF that wasn't the case, WTF was she even brought on for? Disney would've gave her a nice severance and bid her adieu. She was supposed to bridge the gap between Lucas and the Mouse, and she basically took the reigns and turned into a full-fledge suit...the kind that GL despised.
The difference between the Mandalorian and the movies, is that the Mouse doesn't really care about the TV side of things like that. They only care about the movies, since that draws all of their revenue. They didn't even have the foresight to have ANY BY merch in production...so they were playing catchup. They had BB8 ish everywhere 3 months before he appeared.
She's a wizard at keeping things on task budget wise, apparently...the studio bean-counters do love their balance sheets. I agree though, that kind of person has no business having any say what goes into the writing. Especially when their input isn't to the benefit of the story, but just to be hamfisted with agendas. Disney will be only too happy to let her be the lighyning rod and let her take all the heat when they quietly encouraged her in the first place.(Another thing: people aren't going to forget nor forgive what happened to Boyega or Tran, or "the Force is female" or any of that rubbish. I don't know what the source of all that was, directorial rewrites from Rian Johnson/JJ Abrams or whoever, but ultimately she'll take all that blame.)
As far as the merch, that's an ongoing problem even before LucasFilm made it to Disney. Old white people keep trying to force "cool" concepts to move numbers when they have no idea what cool even would look like: Ewoks, Porgs, various iterations of droids, Jar Jar, whatever. They got lucky with Grogu for two main reasons, one, everybody likes cute babies and two,
they didn't let the child speak. Because the second that kid goes "mesa Grogu Binks" or whateverthefck would otherwise fall outta their heads...you know how that dance goes already. They're steadily just throwing things out there to see what works, and 90% of it ends up being trash.
As far as the movie/tv disparity in focus...normally that would be the case, but COVID(and whatever else follows) has them reassessing those priorities big time. They're very canny at setting up themselves for future tech/platforms/revenue strems, and that was always going to be streaming.
