Crystal’s review published on Letterboxd :
The world-building in this movie is INSANELY excellent and the stellar voice cast and beautiful animation really brings this universe and these characters to life. The story is structurally impressive, incredibly funny and thematically commendable (although it ends up biting off a bit more than it can chew). Like "Inside Out," I almost want to give them credit just for even attempting these themes/concepts within a kids movie and they're successful and exciting to a point. I feel like the third act has a few too many acts within itself and could've benefited from a 10-15 minute trim.
Overall, I don't think it's 98% on Rotten Tomatoes fantastic but still one of the year's best so far.
