All four. This is a really good, sharp list of probable factors.
I keep thinking about the long-ago blue-sky ideas Disney kicked around for having Lucas just take over Tomorrowland. *That* is the kind of SW Disneyland fans were hoping for. Colorful, lively, full of comedy, FUN RIDES and a big AA show. Really kinetic and appealing.
Instead, Disney spent a ton of time and money to open a SW land that doesn't look like SW to the GP, and features (so far) one ride that's a team-based video game. Jetson, you're fired.
