The lip sync for KHFM is exactly the same as it was in KH1. I think it might have a bit to do with them switching out the models for the updated ones in more recent games. Their lips were made differently post-KH1 (if you hadn't noticed) and I always found their new lips on their models to be awkward and kind of bad...they seem to have fixed that a bit in KH3D...
But yeah...it's the same lip sync. New model's lips and facial structure probably just makes it look weird.
Also, welcome back! I remember you!
