"A long time ago in a galaxy far, far away..."
Everyone knows the famous opening words of the scrolling text. It may be a bit more about semantics, but how could Tomorrowland be based on a story that is based, "a long time ago?" Moreover, how does this fit into the idea of Walt's famous speech, "Here age relives fond memories of the past...and here youth may savor the challenge and promise of the future." How would we continue to, "leave today and enter the world of yesterday, tomorrow, and fantasy?”
Besides this issue, both Tomorrowland and the Star Wars franchise deserve more. Tomorrowland should serve as a place of optimism, hope, and inspiration for the future. And despite what cynics say, this can still be accomplished today with the right vision. Star Wars is not a "land" but a series of entire worlds. To try to capture the grandeur of visiting Tattooine, Hoth, Naboo, Cloud City, the Millenium Falcon, the Senate chambers, etc. all in one corner of a landlocked park is too much to ask. It would shortchange guests in too many ways. If Disney wants to continue as the industry leader, they must commit to giving more to their guests, not less (as we have seen in TL). Tomorrowland is more than "Spaceland"...it embodies ideas about our future that go much deeper than that.
At least that's my opinion.
