I liked AE too! But I really loved Captian EO!
I was thinking of making an interactive version of EO, let the audience decide the fate of the crew. Have multiple choices. Provide the audience with some type of polling device. Each time you see the movie, it may lead to a new story line. Sort of a "choose your own adventure" type experience!
I think this would be a great way for repeat visits to the attraction.
The only concern is that the majority of the audience may only vote for the same choices on each run of the movie. Thus not being a new experience everytime you see the movie.
