I don't mean to be rude, but I feel like you're throwing up so much information that isn't relevant to a very simple point that it becomes hard to respond.
That simple point was just that the Mark Woodbury introduction to the opening night extravaganza struck a discordant note for how corporate it sounded. I don't think that would be an at all controversial observation if we were to imagine a similar message from Josh D'Amaro (who is the equivalent executive over at Disney). The fix is also very obvious and was mentioned by
@Comped: Just start with Spielberg. So, you wonder why they didn't do that.
Honestly, it's such a minor point and I don't understand the back and forth. Of course I am not suggesting anything about what a hypothetical Disney opening ceremony for a park that doesn't exist would look like. As for Iger's opening day speeches in Shanghai, if anything it reinforces the point that it is better to keep the corporate side of things separate from the showmanship which you're hoping will connect emotionally with guests.
And, yes, WDW's 50th was bizarre. Perhaps the weirdest day in WDW history and the broader celebration was a flop. It doesn't have anything to do with my comment, though.
