Um, Pixar... are you sure about this teaser? I get that everyone thought Cars 2 was too dumb and childish, and that you want to prove it can be serious. But are you sure the best way to do that is to disturb and potentially traumatize the kids who liked it? For the record, I do like the first Cars and I think Cars 2 was okay. I'm sure the movie itself will be lighter, and the teaser doesn't really have bearings on if Cars 3 will be good, but this is a surprisingly dark trailer for a film series most known for selling brightly-colored die-cast cars to small children.
