Also, an expansion based on original ideas could prove just as successful in the long run. But that kind of talk will probably get you tossed out on your ear.
I just think that ship has sailed, at least here in the good old US-of-A. I'd say that DCA would have been their last attempt, and they ended up needing to push billions into that park and inject it with a whole heapin' helping of existing franchise in order to bring it around. Maybe I'm cynical, but I just cant see a large swath of America being excited to visit something akin to Mysterious Island, based on a book they've likely never heard of. I wish I didn't feel that way, I'd love to say that I had faith that if they build an amazing area people would show up. I just don't feel it will happen again. C'mon Disney, prove me wrong.
