And I think it's their Achilles' heel. Pixar is my favorite animation studio...but man (and I say this less as a "concerned parent" than as a wannabe critic) do they have a tendency to take things over-the-top. Of course, you can't be "too mature", but there is such a thing as trying too hard. The incinerator scene from TS3 comes to mind. Even Up, as wonderful as it is, pulls on the heartstrings pretty blatantly. As far as this goes...it kind of just looks dark for dark's sake. I don't think "darkness" or "grittiness" is the cure for the Cars franchise any more than spy cars or redneck jokes are. The tone is interesting, but you can grasp what they're essentially yelling to the audience (namely, "how do you like Cars NOW??"), and that's not a good thing.
