Welcome to Weirdsville, Cartoonland, where automobiles race — and rule — in a world that, save for a thicket of tall pines and an occasional scrubby bush, is freakishly absent any organic matter. Here, even the bugs singeing their wings on the porch light look like itty-bitty Volkswagen beetles.
In fact, Manohla even compares the film to The Terminator!!!
An animated fable about happy cars might have made sense before gas hit three bucks a gallon, but even an earlier sticker date couldn't shake the story's underlying creepiness, which comes down to the fact that there's nothing alive here: nada, zip. In this respect, the film can't help but bring to mind James Cameron's dystopic masterpiece, "The Terminator," which hinges on the violent war of the machine world on its human masters.
Apparently a world ruled by cars is scary to some people, and they feel the need to attack it. Never mind that the vast majority of people feel that their cars are "alive", endowing them with personalities and even names. My recommendation? Go see the movie and enjoy. Unless you're a tree hugging enviromentalist, then go see Who Killed The Electric Car.
