Ultimately, these Disney Star Wars movies still feel off-genre for me. I think that's my biggest issue with these things. Original Star Wars was, at its core, a series of fantasy movies.
I think this is because of a sense of childish wonder that was in the originals. I'd say each director of the newer films has felt like it was time to make more "adult" Star Wars. Since imitating what those films were is probably hard as hell.
I don't think this is bad though. The sequel trilogy in general is kind of a harsh reality, in which the rebel victory was "for nothing" and the og cast is going through a lot of crap. Kylo also feels more real in his anger than any character before in Star Wars.
So I think it's kinda fitting that they feel less like fantasy.
I have to wonder if this was JJ's intention (I mean, he did introduce Kylo), R. Johnson seems to have done this very conciously.
I'm personally enjoying the new movies a lot. TFA is a movie I would have done very differently, I still love it though, and it gave us Kylo Ren, who is by now one of my favourite Star Wars characters.
Rogue One, I dunno. I enjoy it for what it is.
Last Jedi I loved. Some imperfections, and honestly, if you're gonna subvert some expectations, go all the way man. I think it could have been more challenging and interesting than it is, but I'm very happy with what we got.
