Honestly, the little parts they changed or added didn't bug me.
The new X-wing, Han winding up with a different ship because shit happens, even fucking Maz Kafuckup. I'm okay with it. It doesn't feel wrong.
I'm just mad they had to wreck the entire EU to get there, when this totally could have been set after basically all the books.
Don't tell me the main actors didn't look old enough to fit, and don't tell me after Dalla took the GFFA and suchlike there wasn't opportunity for baton passing, so to speak.
