I'm usually someone who feels that when you adapt a story, you can change parts of it- Jurassic Park the movie has a different theme and WILDLY DIFFERENT characters than the book (Alan Grant loves kids, Ian Malcom is a 50 year old bald white man, Hammond was a sociopath). But when it's an adaptation of a story from Japan, that tends to bother me a bit more that it usually gets white washed. Especially sad that two prominent Asian actresses said they would have done it- Ming Na Wen and Constance Wu, the latter one being a perfect idea because while she's a largely comedic actress, Chris Pratt was a largely comedic and look how his career shifted recently...
This is a case, as a sub-sub-sub-sub average writer of fiction, I haven't got the confidence to share anything I write yet, where an audience surrogate or Ishmael or Rashamon-style story would have served the plot better. They could have kept the cast of Ghost in the Shell completely Japanese, but had Scar Jo be around as a transferred detective or overseeing Internal Affairs, that way they could have had their cake (bankable white person to sell to xenophobic Americans) and ate it too (remained a largely Japanese production).
But after being highly reticent of the new Ghostbusters movie going in, and loving it when I saw it, I will reserve judgement for now.
