I wish they would say why they're "not thrilled". Barbie, as a franchise, has a history of animated movies long before the live-action was a thing. I'm more surprised its taken this long, and hasn't been a flood of "We're redoing Barbie and the Three Musketeers with slightly better animation!" while the iron was hot.
There has been, Netflix have done a handful of different Barbie series with multiple seasons over the last decade. Doesn't seem like the next one is substantially changing direction resultant from the film. Feels like the premise for this article was to just reaction-bait its stars.
Ah, so that's where they went. Makes sense. Probably a better market than the old "Direct-to-Video" releases they did.
Well of course not, they want as many of the sequel dollars as they can possibly get. What, they're to share the hype with filthy animators?!
