The grandness of Pirates and IASW is lost without the ceiling as is. Now the panels missing is a different issue. To my point though, go ride Gran Fiesta Tour at Epcot and tell me that the scale isn't lost by having lowed ceilings (and of course a shortened ride). The scale is completely off in that ride because you are so close to the set pieces and they are so large in such a (comparatively) small space.
I'm sorry Pirates and IASW aren't fancy new E-tickets that have SCREENZ and 3d Glasses. If you can't appreciate the scale of a ride like Pirates and IASW, then that's too bad. It's certainly something I would love to see modern day UC take a shot at to see what they could come up with.
This, however, did not deserve a new thread.
