WDW Pirates is the only version I've ridden. With that said it's one of my favorite rides there. I watched a ride-through of the Shanghai version ant it does look pretty amazing. There's much to admire about it. I'm not a fan of excessively projected rides, but it did seem to have a good mix of great physical scenes. I especially liked the sequence of riding between the two ships and some of the subsequent scenes.
With that said, I'm starting to question why I continue to visit these boards. I feel like hearing all the negativity about everything kind of ruins things for me. Maybe I'm better off being in ignorant bliss of enjoying what these classic rides are, rather than letting all the negativity ruin my next ride on PotC because of what it's not, and that it's inferior to other versions.
Nothing is perfect in life... NOTHING. You can't expect WDW to have the best version of every ride. It's impossible, and if that were the case, then the same people would be complaining about the parks being too crowded, and ride lines that are on average 4 hours long because everyone would want to come to WDW. No matter what the situation, there's an endless trough of things to complain about. JMO
My take: let's get more rides and attractions online in dead space, or better yet expand beyond current park boundaries to expand with new rides, not take down popular rides crowding all other rides. Add more capacity first, then that provides a way to divert crowds enough to give classics some TLC. Btw, taking current challenges out of the equation, at times when parks were continuing to draw record crowds that gives Disney no incentive to make any changes. It's a business. When you're selling at record levels, you raise prices and make few changes because you're doing something right according to the crowds. When crowds thin, new or updated attractions would be a way to build excitement and draw crowds again.
