I went and saw this one with the wife yesterday afternoon. No spoilers here. Honestly, not that much to spoil. It's a good flick, very cute, but the story line itself is pretty much a straight line from A to D. B and C don't deviate. It'd be an easy one for kids to follow, and they should enjoy it. Some relatively clever little jokes that got me chuckling pretty good. But I do have an issue.
One of the three little girls in the movie, Agnes, the youngest, had a very familiar character model. It made me sad. I think after Monsters Inc, Boo's parents must have died and they sent her to live at an orphanage. It was the same stinkin' model!
