I think it’s hard for the son of Han and Leia, trying HARD to be a bad guy but kinda sucking at it, not to gather that kind of story gravity around himself (especially played by someone as compelling as Adam)
I get the inverted Vader arc expectation but never saw how that would pay off satisfyingly and that the Duel of the Fates draft bears that out (better script for Finn and Rose, absolute Nowheresville for Rey and Kylo/Ben, imo… and I think TROS is more a reaction to what was seen as not working in that script, while repurposing some of its elements, than anything against TLJ)
I want this movie big time but then again I like the sequels way more than most here, probably… even as an OT gen old-head
