My biggest overall disappointment with the sequel trilogy is probably that it chose, perhaps not all at once, to pattern itself after the originals to the point that it retells the Empire vs Rebels story almost to a tee. It ends in essentially the same place as does ROTJ, feeling like it recapitulate the story rather than truly continuing it.
The most satisfying part for me has been Luke’s journey from traumatized recluse to revivified Jedi Master ready to nonviolently kick ass. It was a gift horse I looked in the mouth, but has been worth being patient for myself to appreciate. This is the diamond in the rough, woven into the soil of the retread that TFA set in motion.
