There's no real conversation to be had, the sooner people come to that conclusion the sooner the pages and pages of back and forth (that will continue for the next 3 years) can be quelched.
Star Wars is interesting because inherently it appeals to a bit of a different demographic than the average DL fan. Not to generalize, because there are obviously many, many exceptions. Star Wars is going to appeal most strongly to pre-teen/teen boys and their fathers in their 4th or 5th decade of life who grew up with the films. There is not a doubt in my mind there will be full-grown men sobbing when they enter that land - and that's pretty much 'happiness' right there.
That is not Disneyland's strongest Demo. Disneyland appeals to the nostalgia laden, American pride, toddlers and princesses, the families, it's thrill seekers top out around 10-12 years of age.
Star Wars is inherently a bit different than what has come before it. That's what people mean when they say it does not feel "Disney", because it does not appeal to their concept of what Disney is in their worldview. Unfortunately, the demo that it does not appeal to is one of Disney's loudest. They simply don't like it, they are upset that Disney is spending so much time, money, real-estate on a property that is not 'for them'. That's a totally fair, reasonable reaction. There is no point bickering about it though, what's done is done. A lot of the other points are just noise to try and make a splashy point, when much of it can simply be filtered out by people who like or dislike Star Wars.
The hand-wringing has already started to cool over ROA since we in recent weeks gained perspective.
This happens every time the demo strays from what people want or expect in a Disney park. The two worst reactions in recent memory were to Cars and Avatar. Star Wars is actually in all context a lot more accepted than either of those two proposals and that's basically all the writing on the wall we need.
The only valid points that weren't either apocalyptic projections, fuelled by distaste of Star Wars or people's desire for it to be in a 3rd gate (Yes, we all want that. No, it's not a realistic plan) were made by
@GiveMeTheMusic. Disney is unloading their absolutely biggest Potter-like Gun on a park that has no trouble attracting guests, and many would say is already attracting too many. The amount of space they are creating for it is admirable and DL is expanding in a meaningful way. The way they are going about it was shocking, but actually appears to have made a lot of acreage with very little impact to legacy DL.
But, DL infrastructure has already surpassed the breaking point. There's a chance this land finally breaks it. That's the only short-sighted thing I can really identify.
