GMR waits became longer when they added it to the FP system. However, it was pretty easy to get a FP.
The problem with GMR was it really needed an update. When the most recent movie you show is 40 years old, it's a problem.
I’d agree an update was needed. It could have been a good ride to highlight some of Disney’s movie properties. Could have had an animation section with Pixar and a super hero section and stuff like that. Have thanos come out and hijack the vehicle.
