Of course it is. You have to realize that Hollywood's top ranks are still made up of rich white liberals whose idea of diversity is having people of different colors act like liberal whites for 2 hours. If they wanted real diversity, you'd have a diversity of opinions where some people would have differing political opinions as well as different opinions on society at large. Opinions that the left might find offensive.
Like say, imagine a world where you have a standard superhero action chick, and yet she's being told that she's a bad example and she should stay in the kitchen/home and do motherly things. But in this world, she's not being told that by the men, who like having her do superhero shit while looking sexy, she's being told that by the women of that world, who think she's a bad example for the girls growing up because they want their girls to grow up to be responsible mothers and wives, not wannabe super-soldiers. That, my friends, is what one can call real diversity, because instead of the "YAS QUEEN SLAY" girl power stuff that you'd see every day where girls and women are always inspired by a super-heroine to go out there and fight, the women in that world think she's a menace and tell her that she's a bad example.
The same thing goes for ethnic diversity. Their idea of ethnically diverse is having just a patchwork of Asian/African stereotypes slapped together and they call it a day. Not to mention the fact that those cultures have differing opinions like say, on homosexuals (some Southeast Asian countries tolerate gays, China doesn't) and their opinions on family and the woman's place in it are greatly different from what the left promotes here in the US and the western world at large. It actually will be hilarious to see the effects of the left bringing in a large amount of Latinos and Muslims into the US, and how that will change the dynamic of traditions and families with time, since both those races believe in strong family traditions and religion, while the left hates both of those.
And as I've said before Africans and Asians make better ethnic shit than the white SJWs do. Asian mythology shows made in Asia are far better and more faithful to the climate because they understand what their people like, and the fact that Africans can tell from a mile away that Black Panther is fake goes to show how minute and pathetic the research they did for that movie was.
