I will be offended if they try to redeem Kylo Ren AGAIN. I want Finn to get the hero's defeated/learn/victory arc and trisect him.

(My biggest beef with TLJ is that Leia didn't shoot Poe Dameron dead.)

The problem with JJ is their habitual confusion between complexity and nuance, and Star Wars can't survive much complexity and requires nuance. (Because the ostensible plot is right up there for nuance with A RAIN OF LARGE HAMMERS; the presentation has to sneak the nuance in.)
