My least favorite Pixar movie is A Bug's Life, but that's just me.
OT: I think Bob's correct about Cars's bad rap... sort of. The thing is, Cars isn't actually about NASCAR. It's about the dissolution of the state highway system.
Living in a large city his entire life, Bob, wouldn't give a shit about this, but America used to be an even more heterogeneous place than it is today. Different areas had a distinct feel to them, because the interstate system didn't exist yet to shuffle cookie cutter pre-fabricated construction and WalMarts all over the country. Today, if there's a mountain, we level it; if there's a river too wide to cross, we fill in portions until we can cross; if there's a natural reservoir, we put one upstream so we can build a road across the empty hole that results. We completely destroy the natural landscape in order to build a more direct, high-speed interstate.
This wasn't always the case. The easiest natural route between adjacent mid-sized cities formed a network across the country. So the route from major cities was often circuitous and winding. Entire communities subsisted on being "rest stops" along these highways, because travelling between places along serpinginous highways that didn't completely eradicate the natural geography took time. These places each had a unique feel, and would often go out of their way to accentuate their individuality in order to become memorable so that more people would stop by. Cars is a story of an entire subset of small towns - small highway oases - dying because of the Interstate system and big box retail stores.
But, of course, I'm sure that he views these places as backwards and racist (whether that's actually true or not), so an entire collection of unique ways of life disappearing forever in the name of progress isn't bittersweet to him at all. He, and most other critics like him, are from metropolitan areas so large, so cosmopolitan, that it may not have even occurred to them, because they were too busy hating the fact that NASCAR is popular in certain parts of the country. Stupid rednecks!
It's funny how Bob hates Lightning McQueen, the "hero" of Cars, but is incapable of recognizing the irony that the reason why he's unlikable, his initial disdain for the people of Radiator Springs, is so similar to Bob's worldview. You're not supposed to like Lightning McQueen, at least initially, because he's an elitist snob who looks down on people because of circumstances beyond their control and accidents of geography. He's more concerned with image than substance.
You know, kind of how Bob hates everyone in America who doesn't live on the coasts.
