Pretty much restating what's already been said: It was much better than I thought it would be, though I had really low expectations because I'm so over Frozen at this point. I thought the projection was really well done, though like others have mentioned, it could have been cut a bit shorter and that would have been fine with me-- it just seemed like it took a long time for the castle to actually get lit up. I have issues with Olaf's size. I was hoping he'd be a puppet or animatronic (similar to what they had in California) and just leave him on the balcony or something instead of the costume. As has been mentioned, the costume's already been seen due to Disney on Ice, which IMO also could have had a better design as well. I loved that most of it was actually the actors speaking and not a recording, though I agree that it was quite noticeable that Olaf was Josh Gad, and the other characters were different sounding. I thought the conversation they had was a little odd, like they mentioned that they should be respectful because it wasn't their castle, and Elsa doesn't initially want to freeze it because of that, but the other characters end up peer pressuring her into it. I just thought that whole setup was weird. It would have appealed to me more if Cinderella were involved somehow, and there were perfect segways into having other characters there but they were never used.
Pros:
-live audio
-castle projection looked good
-mentioning that it wasn't their castle
-music was good
-conversation felt natural
-snow machines on
Cons:
-Olaf's size
-castle projection could have been shorter
-weird conversation/no Cinderella
-I'd be okay if Frozen could stop taking over things that don't need fixing..
