It's at least 80% better than the utter tosh that is The Incredibles (fell asleep in the cinema) and the pure lameness that is Finding Nemo. In fact, after Toy Story, it's their best film to date.
Let's see now...only one Pixar film gets it's own theme-land in the US, racks up millions of dollars worth of merchandising each year, gets Wal-Mart so juicy that it gets Mattel to provide them with exclusive cars, gets released on Blu-Ray ahead of other films AND gets a sequel greenlit, the first sequel of a Pixar film outside of the Toy Story franchise.
