This was an overall very well acted game.

Balthier and Dr. Cid really shined. Ashe, Vayne, Basch and Gabranth stood out as well.

I can't really think of one that was truly awful, but there was an issue with the recording for Vaan and Penello. Their voices weren't "bad" per se (especially not Penello), but they were talking too close to the mic or something.
