I've only listened to a few so far. I'm still not happy with Cloud's VA. Some of his attack cries almost sound bored. Squall's is good, I actually like Zidane's since I never liked his Japanese counterpart. I like Kefka, its not what I would have done but its better than I thought it was going to be. I don't like Terra's sounds a wee bit too chipper and optimistic for the character. I like CoD's but I hate the Onion Knight. Sephiroth's is good.

I still need to hear the rest, I'm mostly concerned about how Kuja came out as he was the other one I felt could easily be screwed up.
