I honestly don't understand what they've done with the VA's for this series and the other voice-acted series. KH had wonderful voice acting, but every time they replace someone, honestly, it's never for the better.
Nimoy is a good actor. He doesn't fit Master Xehanort at all. He can sound grumpy, sure, but that's as much menace as I've ever heard him put in his voice. Plus, he barely emotes in these. Cristopher Lee is the correct kind of voice, if he hadn't already been doing Ansem. You know the guy that did Rasputin for Hellboy? That is basically Master Xehanort - same personality and everything. He would have worked.
- EDIT: If Xehanort had been much older looking (and not "male model old"), Nimoy could have worked well. His voice could fit the unassuming but evil ancient (not old, ancient) guy.
EDIT: My god, I just watched the trailer. Why they thought an OC character could emote is beyond me. There are literally leagues of better, cheaper, female actresses. That one from the WoW web-series, for example. Winry's VA from FMA. SO MANY BETTER CHOICES.
Seriously, every scene with Aqua in it makes me cringe. She sucks at this.
Eraqus's VA is good. Definitely Mark Hamill, yep.
Terra sounds okay, though his scenes didn't require him to emote, so I can't tell if he sucks here or not. I do have to say that I've never been super-impressed by Christian Bale, though.
EDIT EDIT:Based on this trailer, I am seriously wondering whether they let the VA's see what they were providing the voices for. All of the scenes which just make it BLAZINGLY OBVIOUS what tone you should be using, even to the worst actors, are lacking the proper emotion. For example, when Nimoy says "It can only be channeled", he clenches his fist, which would fit with increased emphasis on "channeled", and possibly a pause beforehand ("It can only be...channeled.") Nimoy's reading lacks that completely, reading at the same speed and tone as the rest of the line.
It may just be that SE of A did a half-assed job not in picking the actors (which may have done well in the tryout process), but in helping them do well and, basically, doing the basic job of a director. Honestly, whoever was in charge of directing the actors should be sacked. He did not do his job at all, as far as I can tell. Only the Disney actors, who are intimately familiar with their characters and now how they would say a line, did well, and even then with some trouble.
