Read this article and I must say that I just don't understand that need of everything being interactive.
Through history humans have expressed creativity that then was enjoyed by others in ways that are not interactive - starting with the Greek drama, and continuing with things like the Sistine Chapel, the works of Michelangelo, Rembrandt, Picasso, Monet, the plays of Shakespeare, millions of novels which are considered classics, music by Bach, Mozart or Puccini and so many more. People are still watching TV and movies today - they might do it in new ways and no longer at the fixed time of the TV schedule. They listen to the music on the radio and they still read (maybe not on paper - but Amazon appears to make an awful lot of money with kindles).
I do believe that Disney parks need to be immersive - they need to take you and transport you to another place or time. That's what they are so good at. But that does not have to be in an interactive way! I would even go so far that in certain ways interactivity takes away some of the immersiveness. As I know that I am not from that world, I am a "guest" and don't belong there. Watching passively, I can't disturb that other world with my actions. If I have to interact, that new world is "disturbed". Also, the one's guest interactivity might make other people's experiences less magical.
So - not a fan at all of interactivity being the new buzz word for everything!
