Redemption for Pixar. After Cars 2, I was afraid that part of Pixar had kind of mailed it in and they would start churning out less than par sequels just to make money off of their characters. In this prequel, the story was just as rich. It gave you even more depth to characters that you already loved from Monsters Inc and besides the entertainment value - it taught younger moviegoers that would see this so many important life lessons. And did I mention how funny it was? Just as great as the first entry with the monsters.
I would absolutely recommend everyone check this out. It was easily one of the best "origin" movies ever and Pixar has gotten back to their roots of great story and great laughs for both the children and the adults that take them . . . . . or go see it by themselves.
