Just because I said that I hate Mission: Space doesn't mean I don't like thrill rides! I never said I didn't like Test Track, that's one of my favorite thrill rides. Tower of Terror doesn't even have to be competed with Universal's Doctor Doom. On DD it shoots you up, scares the crap out of you then drops back down and it's done. ToT scares and has a nice dark ride theme to it. Rockin' Roller Coaster is good too, as well as DINOSAUR, Expedition Everest, the mountains and everything else! I don't mind thrill rides, if Disney needs to attract guests, they should have at least 2 thrills in each park. I'm a Disney World fan because of the huge magic they put into their dark rides. Haunted Mansion, Peter Pan, Spaceship Earth and all those are very good! Animatronic Shows like The American Adventure, The Country Bear Jamboree still heart-warming magic. The only thing that usually goes wrong is three simple things that can be fixed: 1) The Lack of updating, Such as the country bear jamboree, they need to take time and update these kind of attractions so it can keep guests coming in, if they don't maintain it properly the animatronics won't look as good and will eventually start to become boring. 2) Replacing, think about the tiki room, alien encounter, and imagination. They were all once great attraction but now they've replaced them with some not-so-good stuff. Whether it's because they're advertising their disney characters, or making it family friendly or whatever. Like Alien, teenagers and adults should have a good time at Disney too! Stitch's Great Escape was a fail because it replaced an excellent thrill, and Stitch's Script kind of lacked. The tiki room under new management replaced a Walt Disney's first animatronic show, and the script is terrible as well not to mention a lack of entertainment in it. 3) would be the abandoned attractions. There aren't too many of these. You've got the Wonders of Life pavilion, Basically half of the Imagination pavilion, and a few rides and attractions that are "seasonal" and forgotten about.
Other than those 3 subjects, WDW is the PERFECT themepark :]
