They should just transfer the Great Movie Ride to DCA.
A lot of people seem to enjoy the projections in the Grand Canyon scene. I just don't see what they add. Like Natalie Imbruglia, I'm torn when it comes to these things. The crude projection of the seagulls in the Pinocchio ride whale scene is charming AF. The Alice in Wonderland projections were awkward and Disney suddenly had the idea they could add animation by projecting it into existing scenes or onto objects, even if the end result was bizarre. Apparently, this also required redoing the voice of the statue in the "Indiana Jones" ride.
The Grand Canyon was a masterpiece of static-ness. A stunning painting that just goes on and on. Time travel some High Renaissance artists to that scene and they'd probably die of a heart attack. The fact that nothing moved not only made it charming, it made sense as you were chugging along on a train, only briefly witnessing its glory. It's why there's very little animation in the highly populated ballroom scene of The Haunted Mansion, another Disney masterpiece from the 60s viewed from on high behind glass with a bullet hole. Now, a Back to the Future lightning bolt sets the Grand Canyon ablaze. How are those poor animals going to escape? They're static and behind glass. It was never that ominous and grim before, even if the lights did dim as we approached the end.
