So, the message of balance this book tries to teach is smarmy and preachy. BUT, the exaggeration through the middle of the book was hilarious, and made me think Cordell didn't take himself too seriously. I laughed out loud when the girl's frolic through the ubernatural world suddenly turned to meeting a soul-mate horse and riding bareback o'er the plains! And things just escalated from there (the gorilla was enough, but then another page beyond that goes even further!). I still can't give it a 4, because the work of the book is to teach me a lesson instead of helping me have an experience. But the fact that I had a little experience in the middle, and that Cordell took charge of deconstructing the message himself, kept me from giving it a 2!
The cartoon illustrations have an animator's quality about them, and the storyboarding shows the animator sensibility we have come to expect from Mo Willems and other illustrators who have worked in tv.
