Tried to watch this with my kids last night and we made it 45 minutes in.
Aside from it being gorgeous, it's also tired, unfunny, and predictable. The main, unlikeable characters' defining traits are their temper and inability to not cry at everything.......
It has the standard, unique/special child being misunderstood by their traditional parents angle present in almost every Pixar movie lately, but with a splash of public utility mystery thrown to give it a plot.
Feels like the quality of an early 2000's Dreamworks animation movie - whiff.
