What I meant by that is that both were written loyal to their characters. Leia is found where we thought she would be: a position of authority "fighting the good fight". Han, may have reverted back to his old life. But he becomes the major supporting character of TFA. Hell, he is the third lead and has a heroic sacrifice trying to save his son. He is the rogue with the heat of gold.Leia (and Mon Mothma) failed to run the Republic so it turned into an incompetent, ineffectual farce that couldn't even put up a fight against the reemerging Empire. To a point where Leia was head of the "Resistance", not the "New Republic Army" or whatever. The new Republic didn't fire a single shot in self-defense before being wiped out.
And Han is a deadbeat loser, who left his wife to hang out with his friend... and he's shit at his job, seeing how he managed to fuck up 2 deals in one day and ended up having his ship boarded by 2 hostile parties.
Neither of these characters were handled with reverence. Leia was kinda sorta treated well in the movies, but when you look at everything that happened between ROTJ and TFA canonically, she's incompetent as fuck and just to add insult to injury, starts some implied lesbian relationship with Holdo of all people.
We could get into the machinations of the New Republic not being effective or Han getting over his head(again). But, in my opinion, I think those are nitpicks..
Luke, on the other hand, is a completely different story. He is on ach-to, for no real reason, other than self-exile waiting to die. If there is one defining characteristic of Luke: it his determination/perseverance. That is completely abandoned, to the point, he serves no real function to the story. They couldn't even be bothered to write, in the context, of his character.....
I still don't understand: if he wanted to just die, why wait? Just jump off a cliff or ignite a lightsaber to your head. What is the purpose of him on that planet?
If he was on ach-to because he believed he could get answers and save everyone. That would have been enough regardless if he was succeding or failing...
