Interesting, was just watching MiceChat's live right now, and they were just discussing how the face has changed already since Monday. His face looks different, skin texture has changed, face is a bit slimmer. What we are seeing now is a short couple day fix, and will get better fixes later.
Dusty watched the show last night with the lead Imagineer for it, and shared his concerns, and they are listening fully, and aware. Mentioned that like at all things at Disney, it's always a work in progress, sometimes they are just incapable of doing more, until a bigger can come.
They are also now doing a speech before the show now, giving more context. Explains the Iger is the narrator, and this is original audio from Walt, and the quality varies per clip, as it is pulled from various places.
He says they listen to what is said online, and take it to heart, that even some of the Imagineers who worked on the project were slightly hurt, as they put so much effort into the show and exhibit, and all anyone wants to discuss is the 3 minute Walt part of it. But they understand if they fix the 3 minute segment, people will be talking about more of the show.
