Sorry, thought it was pretty tastefully done. Yeah was her performance in the style of a less than accurate representation of two cultures? Yes. But she wasn't adopting some obscure accent or going out of her way to poke fun.
If people have an issue with this performance I'd like to direct you to every american made film involving Asian tropes. Or even point you towards one of a dozen ways cultures are being exploited in the media.
Those should be called out more as well; imho.
