Rebutting your example is not "cherry-picking" because you're the one that brought it up in the first place. If you're going to complain about me refuting your example, then pick a better one next time. I'm not bringing up dramas or whatever because that response was geared towards your example. If I wanted to talk about other people's posts, I would've mentioned them in it.
I'm trying to talk about how a character that is supposed to be Japanese is played by someone white breaks immersion, and you're on a tangent about "looking Asian" and stereotypes. I brought up that there are characters that have odd hair and eye color in anime and manga, but are supposed to be Japanese so eye and hair color has little bearing on the character unless it's plot relevant (such as when a character is "half-Japanese"). Himura Kenshin (Rurouni Kenshin) has red hair and blue eyes, but it makes zero sense for him to since he's a Japanese samurai and it's never brought up if he's part European or not. It's not even a historically accurate depiction of the character he's based on.
Also there have been websites claiming that they were attempting to use CGI to make her look more Asian, but it hasn't been confirmed so it's likely a rumor.
I'm not here trying to argue that it's the "wrong" decision. I'm trying to argue that it's a questionable one, and that it can cause some problems with moviegoers in the long run. Especially for those who are fans of the series since the series is supposed to take place in Japan. Having a white woman being the captain of a Japanese police force raises a couple of eyebrows wouldn't you think? If they couldn't find a good Asian actor for the role, then why even use the Japanese setting in the first place? They could have just changed the setting (much like The Grudge or The Magnificent 7) and just state it's an adaption and people would generally be fine with it. Hell, Oldboy was based off a manga but the movie took place in Korea (since it was a Korean movie) and nobody really complained since it was a good movie. Keeping the Japanese setting and using a well-known actor not even the same race as the main character just seems like it's lazy, which is not a good sign for a movie that is supposed to be an adaption of a beloved series (cough Dragonball Evolution cough).
Also, I dunno about you but 98.5% (as of a 2015 CIA report) Japanese in a country with over 126 million people is still a little ridiculous to me. I'm probably just biased since I'm looking at it from an American point of view, but it has nothing to do with the casting decision so I'm not going to get into an argument about that.
