I've had the opposite trajectory. At first I was pumped as a Star Wars fan, for the last few months I've been a bit concerned.
Leave the IP argument aside, or whether the IP fits Disneyland, both of those things are easy to defend considering Star Wars has been in DL for decades.
The point I've never seen been given a good defense for is - each land in Disneyland has diverse and ornate architectural styles, and with many pointing how Disneyland holds the highest number of attractions of any Disney Park, fitting attractions into every nook and cranny, I'm puzzled how a 14 acre land with 2 attractions 'fits' the style of Disneyland?
Adventureland was recently compared to Star Wars in another thread in an attempt to assimilate the two styles. Perhaps the models just have bad lighting, but the planet looks dirty, monochromatic, and not eclectic and fanciful as other, more exploratory lands do such as Adventureland. New Orleans Square is another example of diversity - seeing as you can go from pirates on the seven seas centuries ago, stroll down a timepiece New Orleans street, or visit a mansion with 999 ghosts.
Star Wars: Galaxy's Edge is a massive land set is the same universe and time period - whereas in New Orleans Square and Adventureland both represent many different time periods and adventures, -- and moreover could, combined together, easily fit within the land SWGE takes up.
It's hard for me to see the justification for the way this is being implemented, other than Bob Iger wanted his big IP land in Disneyland, and he's getting it.
