TLJ across the board moves the saga from simple good vs evil to much grayer territories. I like that a lot, I guess some don’t. Maybe that’s one of the big things causing the divide here.
I suspect Star Wars will mean different things to different people. Especially if someone were an old school fan or they start watching during the prequels or they just got into these new movies. But I think most people who grew up with the OT will have a hard time accepting TLJ as anything other than heresy. YMMV
