Kids don’t have a problem with anthropomorphic characters populating their culture and entertainment — just look at nearly every single Disney sidekick (from horses to teacups, monkeys to crabs) — which helps explain a lot of the love that the little ones consistently heap on both the Cars franchise and its Planes spin-off. Adults may have questions about how an entire world populated only by mechanical vehicles works (and the popular theory regarding how every Pixar film ties together, and one which basically makes every car and plane a terrifying war monster, manages to both speak to this and remind us to be careful what we question, because do you want to view smiley-faced trucks as harbingers of human, no, you do not), but the kiddos don’t care. They just like what they’re looking at. But we’re not kids. And we have a lot of questions about how these things work. Next week, Walt Disney Pictures will release Planes: Fire and Rescue, the first (and we’re going to assume, not the last) sequel in the Planes franchise that took wing with last year’s Planes. While the first Planes film was all about a high-flying around-the-world ariel race, Fire and Rescue is about, well, fires and rescues. Lead character Dusty (voiced by Dane Cook) is back, but now he’s working on a new career: as a plane dedicated to snuffing out fires and leading rescues in what looks to be a massive national park. It’s a cute premise, but man, do we have some questions. Here’s what Plane: Fire and Rescue needs to answer for us.
