Oh you mean why are STAR WARS fans obsessed with not having THE ACTUAL STAR WARS people give 2 craps about being in the land? Is this a real question? If you are a Star Wars fan and have to ask this question then you are not a Star Wars fan. Everything we know about Star Wars came from the OT. Star Wars at one point in time was just a series of 3 classic movies. I never cared about the original EU or any of the stupid cgi cartoon shows. Same with most. Star Wars was never meant to be this great expanded universe. It was a fairly tale adventure with space and aliens as its frame work to tell the classic heroe's journey. That story ended 40 years ago after Return of the Jedi.
If you told anyone back in early 2000's there would one day be a STAR WARS land and told them there would be no LUKE,HAN, LEIA, VADER, LANDO, or any of the locations known from the films they would have called you a liar. The land should have been a celebration of all of Stars Wars and mainly included the OT characthers with some perquel and new trilogy characthers thrown in. Luke Skywalker is Star Wars. The ot characthers are the liscense. that is why the whole thing cost disney 4 billion. Notice how the thing people are talking about from the upcoming films' trailers is the Emperor and how he is back and no one is talking about Poe, Ray, Finn, Rose. everyone is talking about the Emperor. there is a reason for that.
