So applying this logic you would agree that Dumbo, Peter Pan's Flight and Snow White's Adventure shouldn't have been built and oddly enough, stood the test of time, because of a movie tie-in?
While it's true that Walt's Fantasyland attractions were named after and in some cases retold the stories of his films (slightly), they WERE NOT movie tie-ins. What! you say? Please hear me out on this.
Attractions like Snow White's Adventures, Peter Pan's Flight, Mr. Toad's Wild Ride, Alice In Wonderland, etc. celebrated the films that built Disney. But you can't confuse those rides and their themes with the "enhancements" that were intentionally made to promote a current Disney film. There is a difference between celebrating classic Disney films and promoting new ones.
In the 1950's there were no movie tie-ins to Peter Pan, Alice, Snow White, Dumbo, etc. What was there to tie into? Home video was decades away. Television was new, and these movies only lived on film. They were occasionally re-released in theaters, but those releases were few and far between.
My point is quite simple. You cannot compare what Disney did to POTC to Walt's originaly intentions with his attractions. The argument makes no sense, and is just a way to defend the company's exploitation of their latest "fad" franchise.
I am glad this thread exists because people are starting to see that these changes to classic Disney attractions are not a good idea. I have always said that if the pirates movies were so great, then Disney should, and could be able to justify imagineering a brand new attraction based on the films. Changing the POTC rides just shows that the company does not believe that the films can stand on their own, justifying a new attraction. Or that imagineering can no longer create quality "dark" rides.
Walt Disney's original films are what built Disneyland. Those original attractions from over 50 years ago are still there because of one simple thing. All of those films are enduring classics. Nothing comes close to them. The Pirates movies may be blockbusters, but there is nothing enduring about them. As one poster pointed out, they are forgettable, and will be forgotten after this franchise ends.
The Haunted Mansion was Disney's last great "dark" ride. Nothing has come close to it. From Adventure Thru Inner Space, to Pinocchio, to Superstar Limo and even Buzz Lightyear. The mistakes have ranged from corporate being too cheap to spend the money for a quality ride, to imagineering screwing it up. Now the "S" word is being used to ruin perfectly good attractions. Disney has taken synergy too far. They need to create an original hit, an enduring hit, and then build an attraction that is worthy of such a hit.
