The thing about screens is that they are already old-school. We can watch shows AT HOME NOW on screens EVEN IN 3D (a friend of mine has a 3D TV and it's awesome, aside from the heavy glasses.) Theme park rides are supposed to take you to places you haven't already been. Well, when it comes to screens, anyone who has a modern TV has been there, done that, so come on all you theme-park ride designers/financiers, cut it out with them already! There's nothing amazing about them anymore. They're not even convincing. Look at the Hitchhiking Ghosts in the Haunted Mansion. Those screens are stupid. They make you think you're watching a cartoon, instead of something real that's happening in front of you, like the old effect did.
And just when AAs were really coming into their own, too, with all the great software and mechanics and stuff. Oh, what Walt and his original Imagineers could do with those...or, better said, WOULD do with those, as opposed to the people who build park rides now. What a gyp.
