The amount of people you see walking around with droids or Savi Lightsabers speaks for itself, but where they've gone wrong is where Potter hit a home run - Food & Beverage. There's really nothing too special about the quick serve places and there's almost never a line to buy Blue/Green Milk.It doesn't cost $1B to build a cool new ride that excites the hard-core Disney fan base. The real point of GE was to sell merch and upcharge expereinces. And Disney rushed ahead with an unproven property that hadn't shown it could do that yet, and ultimately proved it could not.
If Disney can fix the F&B situation and drop the timeline, then I think the land starts to make a ton of money. Imagine if there was a Baby Yoda experience in the land that was upcharge. Unfortunately, they can't do that right now because of the stupid timeline.
