Here's my eulogy:
When I visited in 1989, the Great Movie Ride was THE attraction at Disney Studios. Honestly, it was the only attraction in E-ticket, dark ride terms, but nonetheless it was high tech and revolutionary for its combination of animatronics, live actors and storytelling.
I remember The Disney channel was constantly running specials on this new park and how this one attraction was a landmark achievement. The Wicked Witch was pretty much the unofficial mascot according to them, with imagineers and promotional hosts often pointing out how amazingly lifelike her movements were. The Aliens came second, with the right side Alien often being featured in promotional shots and videos as well.
Over the years, the attraction kept on moving. It was not only at the center of the park, but THE center of the park, pulling the idea of the movie studio together like a bow.
Over the years we all floated the idea of changes coming- constantly tinkering with thoughts of Tarzan or Alien being replaced by "Lord of the Rings" or other movie franchises. Alas, none of that was to come.
Disney in 1989 was a company with few live action franchises and a sense of dignity, and they tried there hand at creating a not only unique celebration of the movies, but they were smart enough to get in bed with several non-competitive studios to flesh out an attraction so it didn't become "the Great Disney movie ride".
Flash forward to now, and Disney is a conglomerate media powerhouse with Pixar, Marvel, LucasFilm and their own studio branches turning out hits. They no longer need to recognize the past or anything they do not own, and the idea of a studio park in this day and age is, for all purposes, dead. Tastes changed, times changed, technology changed, but the Great Movie Ride kept chugging along with this interesting idea and story laced through scenes from popular movies (from years that had past).
Disney is building a Star Wars land. A Toy Story land. It has an Indiana Jones show and a Star Wars ride already. It celebrates its animated films in montages, fireworks, and many other attractions at other parks. Great Movie Ride has always had an expiration date in the modern Disney age, whether we wanted to admit it or not. The true sadness of its closure is this- it's the end of the moving theatre ride, it's the end of the mass animatronic storytelling ride, and it's the end of the interactive live action ride. It's three giant endings in one, and that's why people cherish it more than other attractions.
The new Mickey ride is sure to be a treat, and I'll be sure to check it out. But it won't have the massive sets, the immersive detail. They'll be no "Tom's Livery Stable" or real dynamite explosions. They'll be no gangster shootouts where an actual car rolled into the scene. They'll be no John Wayne warning that you're entering dangerous territory before coming face to face with terrifying Aliens, snakes, and the Wicked Witch. Never will there be such a blend of random classic movie characters in one place (unless you pop in Who Framed Roger Rabbit).
And that is why the Great Movie Ride is such a bittersweet end.
