What do you mean I can't have it both ways?
Xion is HER OWN PERSON. Kingdom Hearts isn't some low budget, bargain bin game. Disney can afford to pay for a voice actor to be one character only. I liked that Hayden was Kairi and Alyson was Xion, and Alyson does Xion perfectly. I just don't think she's right for Kairi, and I just feel it's unfair that when Kairi finally gets the focus, Hayden doesn't get even a phone call.
Now now, no need for the all-caps. We're just saying, and like
@palizinhas said, they're supposed to be identical. Xion is her own person, yes, but her origin is undeniable: Sora's most precious memory, the person always on his mind. There's nothing wrong with that.
Think of it this way, the Nobodies are identical to their original selves, and even Roxas falls under this rule due to Ven's heart sticking inside Sora's body post-stabbing. Replicas don't have to be any different, and they're sort of a subspecies of Nobody anyway, so it's fine. If it's any consolation, Xion has black hair so...that sets her apart from Kairi (no, you cannot use Naminé as an excuse for many obvious reasons. The canon information already forbids it, and we're not going to do a repeat of the shipping thread fiasco).
Can Nomura fire SENA (whatever that is) and the voice director? I remember reading/hearing in interviews that they were very specific and involved in getting the voice work down perfectly - which showed in previous numbered titles. How is it that for the numbered title with the biggest budget, the biggest hype, and the biggest cast, the voice director blew it? He didn't even call Hayden!
No, he can't. The fact that they screwed him over with XV tells just how little influence he holds in headquarters. The most he got away with is screwing over animation directors with Lulu's belt dress.
Also, this:
I don’t think Nomura can fire the entire North American branch of Square Enix.
If he has little influence in headquarters, he has much less, if any, at the NA subsidiary.
And this:
Bob Buchholtz is a highly respected voice director with dozens of titles under his belt. He did the voice direction for FF7R which was pretty great, and previous FF games before that, and like all of the KH games. I think there is honestly an issue with the disparity between what Bob would likely direct and what the Japanese staff that listen in want from these vocal performances.
Man's experienced. Can't argue with experience.
I do wonder if there are any Disney employees involved with the original character voice production though, besides the VA's I mean.
