I never was able to buy into the Cars concept. I mean, it was about a world where the cars themselves were the people, and they watched the races in these fantastic stadiums, and filmed them on cameras so the races could be projected on these enormous screens, and they lived in these cute car-friendly motels and everything...
HOW THE FREAKING BUNNIES WERE ALL THESE THINGS SUPPOSED TO HAVE BEEN BUILT???
CARS DON'T HAVE HANDS!!!
The whole thing just didn't make much sense.
At least with Happy Feet, the penguins weren't supposed to have built things they logically could not have built. (And it was a cute story, too.)
