This. I don't really object to any of the voices, the only thing that bothered me a little bit was with the Al Bhed, that their English sounded the same as everyone else's..... Like, you know how you have your French accents, your Australian accents, your Indian accents..... why wasn't there an Al Bhed accent? Brother sounded French when he spoke English and Cid sounded like a southerner. It just didn't seem like they were their own race of people.
I know that it sounds heaps petty, but I just think if you're going to invent a language, do it right :/
Yes, I felt like there should have been a consistent Al Bhed accent that Rikku and her family, at the very least, should have shared. My least favorite voice in the Final Fantasy X series is the voice for Brother. His name, his character, and his voice bother me greatly.
