1. Characters such as Marluxia, LARXENE, Zexion, and Lexaeus are even more empty than they ever were. I understand, there was a very short time to see them. But they could've build something more. We could've seen conversations between Marluxia and Larxene while Roxas was around. Or how Zexion and Lexaeus interact. We could have also seen some flashbacks into something relevant about them. i admit i liked Saix a little more, but not enough to say it was amazing.
3. XION! she is an interesting character at best, but i hold absolutely no love for someone who is just there to recycle plot. i guarantee if there was more voice acting, her character would seem even MORE empty just because we can see her get emotional all day, but not really do something unique that tells us what kind of person she is. She really really bothers me because theres this level of gender-issue when in the end she looks like sora at the end. It just throws me off. She should've just had Sora's voice.
