The only thing I am worried about is that Aqua's voice actor will....stop in the middle....of sentences....and ruin the whole thing. Hamill and Nimoy I am not worried about but so far all of these actress-voice actors (Xion is a big offender) don't have good delivery.
Well that has to do with fitting the mouth flaps. In Days, none of the faces were reworked for the english lines. So in order to keep it from looking to shitty, there had to be pauses when the mouth flaps stopped moving to the (Japanese) words.
