Eleanor LOVES Monsters, Inc and Monsters University. In fact, we watched MI three times yesterday and are watching MU as I type this.
That being said, this book is terrible. It makes no sense and can't even be called a movie adaptation. Even Eleanor was confused and hardly paid attention. That means a lot, since she loves Sulley especially.
Also, it wasn't even accurate, ignoring the whole 'leaving Boo at the park' idea. First, monsters don't go through bedroom doors, they go through closet doors into the human world. And technically, Boo wasn't her name, it's just what Sulley called her.
Waste of money if you love the movies as much as we do.
