Go see Up! Right now! I'm not joking. It is awesome. I won't even go into detail about what was great about it. The only minor complaint from me would be the weak villain. He was menacing. He was cruel. But he also seemed to be played out before in other animated (and live-action) films prior to this masterpiece. Initially I gave Pixar's 10th movie a 10 out of 10, but I am reconsidering it a nine with the weak antagonist.
Overall though, it is incredible. Great storytelling. Visually stunning. Funny, sweet and genuine all in one. My updated rankings of all the Pixar films (who have made one great movie after another) are as follows:
1. The Incredibles
2. Toy Story
3. Finding Nemo
4. Up
5. WALL•E
6. Ratatouille
7. Monsters, Inc.
8. Toy Story 2
9. A Bug's Life
10. Cars
