There's a deeply frustrating infantilisation when something is localized in the same language. My kids and I love Bluey, an Australian show, but apparently the producers had to refuse to have it redone with US and UK accents to stop it happening. Never understood what the problem with having David Attenborough instead of Sigourney Weaver narrate Planet Earth was either.
Bluey is a fantastic show, and the fact that it's unapologetically Australian is part of what's so fun about it. I think it's just the choice of nervous higher-ups to localize things like this, and not actually what people want. Like Douglas Adams says, people can survive hearing references they don't understand. And they might even learn something about another culture.
The exposure to places that are not-America is good for them!
