Quick point/semi-rebuttal:
The fact that people are walking through the theater NOW isn't really evidence they don't want to watch the movie.
It could be based more on confusion with the new setup (heck, *I* got confused by it last month and wasn't sure if they were trying to keep people moving in order to clear out the pavilion before IllumiNations).
Or you could have people who would be inclined to watch it, if not for the fact that other people would be tromping through the theater during the whole show. (I sat down for a minute or two during the film, but I just couldn't relax or get into it with the doors open.)
Now, if people were rushing to the far doors in droves under the old setup, then that would seem to be more analogous to that very nice flowerbed anecdote.
