Other than these songs, there is nothing specifically negative about the movie. The whole idea is clever, and the messages about society to real life are nice, but the story element is a little lacking. The whole resolution and how the movie gets to its ending doesn't make sense. It feels lazy the way it wraps itself up. Not only do the events that lead to the end of the movie feel wrong, but the ending itself doesn't make sense.
I guess you can explain away the story faults by saying it's a children's movie but it's still annoying. I want to reiterate that the movie ends up being fine. Even though it definitely has its problems it's still the best thing you can take a child to see in theaters right now.
All the visual jokes were in the trailer
