Again, kinda damned if you do.
Time skip and the Republic is thriving, get slammed for being totally unrealistic. CF Star Trek. Actually being somewhat realistic in that the New Republic is hopelessly unqualified to run an actual government, and get slammed for not giving our OT heroes a happy ending.
Either way, someone's going to bitch about it. Might as well pick a lane and stick to it.
Then again, it totally didn't bother me that the OT heroes didn't have a happy ending. I never thought that they would. Heck, even in the Expanded Universe, they don't ever get a happy ending. One thing that these new shows - Obi-wan, Ahsoka etc - are doing is filling in the gaps in the Prequels and salvaging the stories there. I wonder if the later shows will do the same for the last three movies.
