Cars is the only Pixar movie I didn't finish. I just didn't like it at all. Because of that, I didn't even bother watching Cars 2.
I pray that Pixar takes the Cars franchise, loads it into a rocket, send the rocket off to space, then shoot another rocket which will collide with the Cars rocket and obliterate it.
Aside from that, Pixar is in another league. The Incredibles & Ratatouille are my all time faves.
