I went to see "Monsters University" with my nieces while we were vacationing at the beach. It was worth the drive - and running through the rain from the car to the theater. :-)
If you haven't seen any previews yet, let me give you a brief overview. The action takes place before the events in "Monsters, Inc." Mike and Sulley are just beginning their college days and meet for the first time. Let's just say they don't become best friends right away. They both want to be in the Scarer program. Mike studies really hard and can answer any question the teachers ask in class. Sulley comes from a famous family of Scarers, so he thinks he can pass easily without even bringing a pencil to class. We get to see what happens as the school year goes by.
It is rated G and is fun for the whole family
You can play around on the MU website or watch a trailer on the Disney website.
Here's my ID from Monsters University. (Like all ID photos, it's not perfect.)
