I got wind of this about a week ago—my info was clearly later than Lee's or Martin's—and I've had conflicting thoughts. Five years ago, the GMR was an embarrassing relic of the late 80s, hidden behind a giant plastic toy. The ride's pacing, broken FX, awkward script, and even more awkward CMs overshadowed the impressive sets and AAs. Then TCM stepped in as the all-too-obvious sponsor and financed a complete overhaul. Last time I rode it, everything worked. The AAs were smooth; the FX were functioning; the new prerecorded voiceover mostly covered for the bad CM acting. I could see the potential for future updates, and the ride didn't seem so moldy anymore. Most importantly, the ride introduced guests to some of the best movies ever made.
The Mickey attraction will be incredible.
@marni1971 can correct me if I'm wrong, but from what I'm told, the cuts haven't been substantial; this thing will almost be Blue Sky. It will be a worthy E-ticket, although a bit too short.
As a kid, the GMR was pure magic. As an adult, I don't consider it an irreplaceable classic. The attraction was really good, but not on the level of POTC, HM, or Horizons. I just hope that Disney maintains the Golden Age of Hollywood in this park's transformation.
