Bluey runs on repeat in our (American) house and I'm sure I've seen each episode a half-dozen times now. I find the Australian accents and cultural references to be a charming and fundamental part of the show. The wildlife, the fauna, the building designs—it all screams "Australian" at you, so hearing a bunch of American accents in that setting would be jarring and out-of-place.

The Aussie themes have even led to some history lessons in our house: a handful of episodes reference Australian soldiers (including Bluey's grandpa) which led to my kids asking what wars Australia fought in. Queue the (very) gentle introductions to WW1 and WW2, and the Pacific War specifically.
