I'm excited for these but I would not go so far as to say optimistic. My optimism is tempered by the knowledge that Disney will likely treat these lands as they do all others. When something that adds to the "awe" and "wow" of the lands breaks they will just ignore it and act like it was never a functioning part of the land in the first place because "guests still enjoy it". For proof of this you can make an appointment with the Yeti in EE. I see water falls ceasing to function properly and getting turned off. Sound effects in the foliage not working correctly so that gets turned off too. Then the bioluminescence stops working in sections and never gets fixed. Believe me, I am not trying to sound like a doom and gloomer. Not at all. It is Disney's past behavior that has me thinking this, and not just because of the Yeti. They are going to have to prove that they give a crap about the parks maintenance before I get optimistic about their lands and the impact they will have on me.
