BTW, it seems my perception is not the only one. The following blog also highlight a similar opinion:
Here is a quote:
kirk: My point wasn't quite about racism, it was more about exploitation of a culture that is routinely treated as "exotic."
And since Asian Americans aren't always as mobilized as black Americans, they sometimes don't throw down over these sorts of things, even if they annoy them. This obviously wasn't worth a full assault. It's more of a minor infraction.
Most Asian's love Mulan because Disney worked closely with the Asian community to make it and it was based on their history. It's about what's tasteful and what isn't. It's a fine line. And Lucy Liu and Jackie Chan are routinely criticized in the Asian American community for the choices they've made in American cinema.
So my point really wasn't so much about the film, but how Asian Americans don't see representations of themselves as just people, not kung fu masters or cartoons, but just people in cinema.
That doesn't mean it's necessarily a bad movie, but it is part of a cycle that continues to only dramatize the parts of Asian culture western audiences are most fascinated by.
