I am fairly certain you've ridden Shanghai's POTC, which makes this comment even more deranged than it seems at first glance. At no point does Shanghai Pirates stop moving, and at no point is the primary action of the ride occur on screens. The screens act as a backdrop and world-building but not as the primary focus.
Honestly, reading through your comment, I really don't see how it's possible you've ridden this ride. I think you've done exactly what you say is possible with screen rides, watched a POV at home, and are casting judgments.
Riding Cosmic Rewind feels DRASTICALLY different than we could've expected from leaks, clips, or even a POV. Riding Tron feels DRASTICALLY different than we could've expected from leaks, clips, or even a POV. So while these clips or existing POVs are nice, since some people have ridden Tron, they can attest to their experience.
While I was in Shanghai, I chose to ride its POTC around a dozen times and Tron about four. I believe I rode Roaring Rapids about 3 times, but no other ride captured my attention as time as much as POTC, but Tron was second.
Very solid ride that I'm happy is coming stateside. I wish it were longer, but its ambiance is far more valuable than its on-ride experience (similar to Journey to the Center of the Earth in Tokyo).
