The kids liked it a lot, especially the music, and what more can you ask for? Well, you could ask for a Pixar movie.
The last two thirds of the movie has good suspense and a good beat. Any child under twelve will stay in their seat for a while.
Since it is set in New Orleans it also has to dance around some tricky topics, such as racial harmony, massive economic disparity, and Cajun identity. It also builds on a dreamy vision of New Orleans that Hurricane Katrina washed away. My twelve year old was asking all types of hard questions afterward about all the stuff the filmmakers glossed over.
It is a good time if you suspend disbelief. Just do not expect too much.
