Wicked for good was.... okay

I was expecting a lot more than I got tbh, and I was left wanting so much more. Like the end made me just be like so they're off in some random desert going who knows where? And Glinda is just stuck with the mess of fixing Oz all by herself? Thinking for the rest of her life that her best friend and Fiyero were killed and probably feeling super guilty? Also the fact Nessa was just randomly rolling herself through munchkinland in the middle of a tornado???? Like mama she's the governor, and ya'll are telling me the governor didn't have any guards with her, let alone someone rolling her around
