I wouldn’t exactly call the shows “knee-jerk reactions”. That would be the Frozen sing a long (which I think is pretty cute, despite the low budget). I never saw the Pocahontas show, but Hunchback was a favorite of my family’s. It was creative, it handled the plot really well (and it started out with a murder, welcome to Disney world!) and the performances that we saw were better than what Beauty & the Beast is pulling now. And Disney had the shows ready to go on the films’ release dates (I get that the Hans reveal in Frozen would have been a massive spoiler, but that could have been sidestepped).
I really hope that Coco being on Netflix helps its popularity grow. While I don’t think I can watch it again right now (lost 3 grandparents recently, last one was a month before Coco came out in theaters), it’s arguably Pixar’s best since Toy Story 3 (though Inside Out ranks high up there for me) and I would love to see it become incorporated into the parks. It isn’t one that lends itself to sequel material, so I would really hope that Disney figures out a decent timeline to put it in Epcot.
