The complaint about a lack of Disney in the park isn't solely about IP's. It's that the types of magical original experiences like Big Thunder, Tiki Room, Haunted Mansion, Pirates of the Carribean, Space Mountain, Matterhorn, Primeval World, Country Bears; these attractions were missing from DCA. In any form. DCA opened with an original darkride based on ABC's B-list celebs, Soarin (a bare bones concept of an attraction without any Disney magic), a lifeless but pretty rafting ride, a fake wooden coaster, and that's it for major rides. Nothing had character. We didn't need Disney characters per se, but we did need some level of characters and story to be present in the park.
Had DCA opened with a Gold Rush themed rafting ride filled with music and visual gags like Pirates, Buena Vista Street, a Hollywoodland that featured Dick Tracy's Crime Stoppers and a Great Movie Ride that focused on Disney Animation, a fully themed Soarin, Discovery Bay instead of Paradise Pier, and a Spanish Mission-themed area with a Zorro-themed E-ticket; we would have a very different history of the park. A park with 4-5 brand new, never before seen, world-class Disney attractions. Give me an Alien Encounter but themed to Bigfoot or the Wendigo in Grizzly Peak and you have a park with a lot to experience and offer.
Instead we got a park full of carnival rides, the design of the Orange County Faire Grounds, and a few E-tickets that were fun but lacked the quality and charm that we associate with Disney.
