But imagine going from Jungle Cruise to Pirates and being charged another day's admission.
You're paying twice for the same themed land.
You tell an average family that Universal Orlando has a Harry Potter themed land but then you say..."Wait a minute, we divided this up between two parks so we can charge you more to experience the whole thing." And that is supposed to elicit a positive reaction?
If Phase 2 is as well executed as Phase 1, you can be sure that the positive reviews will far outweigh the negative ones. The increase in attendance last year was for people that wanted to see Harry Potter. Sure there were those theme park fans that were indifferent towards Potter that wanted to see the ride system, but at it's essence, people were paying for the franchise and Universal delivered.
Having said that, the quality of the land isn't a function of Harry Potter, it's a function of Universal Creative, Warner Brothers and JK Rowling working together to create something great. They could have done the same thing with another franchise, had excellent execution but not the fans. It doesn't mean that the other product was inferior to Potter from a creative standpoint, it just means that it's a harder sell.
This is what Disney is facing with Avatar. The movie lends itself to an incredible immersive environment, but the selling point of the franchise is no where near that of Potter. Disney could create 3 E-Ticket attractions for Avatar that are all universally lauded for their design and experience. But the fan community for Avatar isn't as strong as it is for Potter - as such, the percetion would be that Disney failed because they didn't get the ridiculous boost that Universal received from Potter.
All I really care about regarding a franchise is "does it lend itself to an immersive environment." Harry Potter lends itself to an immersive environment, as does Avatar, Cars, Lord of the Rings/The Hobbit, Star Wars/Lucas, Tron and John Carter all lend themselves to immersive environments. However, there are obvious disconnects between each of those franchises. Harry Potter, Star Wars and Cars have huge merchandise lines and the first two cater more towards adults with that merchandise. If Disney is looking to compete with Harry Potter, Star Wars is the only viable franchise to do it from a marketing/merchandise standpoint. All of the others could compete from an "immersive environment" standpoint, but that's not the entire story.
