It is very cute and at least worth seeing once. More than once, probably only if you have small kids.
From an adult without kids perpective, first time I saw it was at midnight during a preview, there were NO kids in the audience, adults played all the parts. That was a blast. But it's for the kids, they'll cast a couple of adults in certain parts though.
If you love Belle, it's a small space for the show, like a personal party with her. Well done.
