Having had time to think the movie through, I think one main problem with the film is that there is no strong central relationship focused on in the movie that would heighten the emotional stakes. I don't mean there needed to be a romance, but some kind of dynamic to latch onto.
Encanto had Mirabel and her family, Frozen had the Anna/Elsa sisterly dynamic, Tangled had Rapunzel and Flynn, BIg Hero Six had Hiro and Baymax (who is a stand in for his brother Tadashi).
I feel like the filmmakers couldn't decide whether the emotional center of the movie is Asha's relationship with her grandfather, her friends, the Queen or the Star....so they kinda tried to do them all and ended up short-changing all of them. Really the only character relationship I found particularly compelling was the complicated marriage between King Magnifico and his wife, and that's only a subplot.
