I agree it really undercuts Luke and Han’s development for them to have failed in the same ways they seemed to grow from like relapsed addicts. Just wanted to add again why it’s also different for me when Luke has seen firsthand the living proof of Vader and all the destruction he’s caused he still says he cannot kill him to Obi-Wan, and then to Vader, so it yes for me it is extremely abrupt to the point of whiplash when Luke reacts to his defenseless nephew’s dream. Maybe if it were depicted visually as a premonition it would have sold better for me, but I feel like I’m just taking his word for it that the thoughts were seriously super bad, I don’t know it just doesn’t seem organic at all.

EDIT: I typed all that out just to see Dre’s post already covered it haha
