Honestly, Disney's mistake, for those who believe there was one (and I understand there are those who believe there wasn't) might have been setting the expectation that THIS immersive land was going to upend the Boy Wizard down the road, reclaim the title of Most Innovative Immersion In A Theme Park from Universal, and draw not-ordinarily-theme-park-people to Disney. Because that is what was telegraphed, and so far, it hasn't materialized (thereby causing some to focus on the fact that it hasn't materialized and driving everyone who loves the land crazy).
If Disney had either (1) set the expectation that they were going to create a elaborate and meticulously detailed Star Wars-inspired land for Disney fans; or (2) followed through on a lot of the immersive elements that were either cut (stunt shows, aliens, Equity actors, droids and drones rolling/flying about) or that were never feasible to begin with (personalized interactions with CM's depending on your chosen alliance and skill on MFSR), they might have gotten there. They might STILL get there yet, as ROTR should completely reset the bar for theme park rides if it works as advertised, and there is no reason they can't decide to invest in stunt shows, aliens, droids, drones, etc.
