But at least it shows that they put in a lot more effort than The Simpsons. Having a stereotypical character isn't necessarily all that bad in itself if it's balanced out by other characters of the same demographic who are different. In The Simpsons, every Indian character speaks exactly like Apu until they got an Indian actor to play Apu's nephew Jamshed in season 27.
In King of the Hill, every Laotian character doesn't sound exactly like Kahn. Kahn, Connie, Tid Pao, the Wassonasong family and Laoma *all* sound different from each other. And they're not all workaholic tiger parents like Kahn and Minh. They all have different personalities, jobs and subcultures.
