No matter what, Galaxy's Edge was worth it for Rise of the Resistance, one of the greatest theme park attractions ever built. Would I have preferred Discovery Bay? Yeah probably. And I agree with the consensus regarding dead space, lack of kinetic energy, Smuggler's Run being a disappointment, etc. But as long as Disney/WDI is open to tweaking and expanding Galaxy's Edge, I don't see its existing shortcomings as impossible to overcome. And again, we got Rise out of it, a phenomenal addition to Disneyland's already-stacked lineup of E-tickets.
Do we know the extent to which expansion plots are available? IMO ideally they could put something low-key/indoor/hidden (to preserve the sensibility of resistance forest) in plot 1 (Dagobah System boat ride a la Navi River Journey?), something kinetic in plot 2 (flat ride? outdoor track ride a la Tokyo DisneySea's Tinkerbell's Busy Buggies?), and a large outdoor attraction in plot 3 (Luke & Leia's Magical Creatures Speeder Bike Adventure?). But who knows if these spaces are actually workable.
