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.
Edit:
> Actress and conservationist Sigourney Weaver was brought in to replace David Attenborough as narrator, as it was thought her familiarity to American audiences would attract more viewers.[0]
