In my handful of visits to MK, I never wanted to see the show..it held no appeal for me whatsoever. I remember, on my first visit in the mid-1970's, my Mom went to see it by herself, while my Dad took me and my sister and brother on Haunted Mansion.
While I definitely have a penchant for nostalgia,I think this may have been a wise move. Like a previous poster wrote, other attractions have gone under the knife in similar ways and come out that much better. I think that this is in fact a clear example of Disney's work ethic:
"Whenever I go on a ride, I'm always thinking of what's wrong with the thing and how it can be improved." - Walt Disney
