WH you nailed how I feel. That it is disjointed and not connected at all to TFA. It's just there and it answers nothing, provides nothing, doesn't push the plot forward at all and what IS the plot because it is so different from what we left out on with TFA?!
AGAIN SPOILERS BELOW; READ WITH CAUTION
There was definitely GREAT moments in the film. I also wasn't against more gritty Luke. I just do not for one second believe he would do that to his nephew. I also hate that we didn't get more reaction to Han's death from Luke.
I like the turning some tropes on its head i.e. hair-brained plan miraculously worked...I just think those inversions were very poorly done. I think meditating on failure (with Luke, with Finn/Rose/Poe) is great, but again, execution was not good. I was actually happy Kylo didn't turn good suddenly and this movie did make him more interesting to me. But he still seems immature. But room for growth
The reunion scene with Luke/Leia/Carrie/Mark had me in tears, but it felt like an after thought.
I just feel it was very weak storyline wise (so many plot holes). I am not someone who is hyper critical of movies and I was also not someone who was invested in the wild fan theories out there before the movie. I went in kinda expecting anything to happen, but it was just not a great movie. As I said, it was "fun" but lacked the heart that made the series so beloved even with its faults.
I do like some of the subversion of ideas about the force, but I still think it dumb to make it something you just pick up with no training. Raw power is one thing, but to have training in it?
In the end, there is a lot of built in lore with SW, and I do not mean the books and comics. I mean just from the movies themselves. I feel like Kennedy doesn't respect that and as a result TLJ lacks that overall connection to me as a major fan. It was a bad movie for world-building.
