When I first saw TLJ I left the theatre asking myself "did i like that?".
There are some great parts of the movie: the relationship between Rey an Kylo. The death of snoke and the ensuing fight. The hyperdrive manoeuvre. I really liked Luke's characterization and the reveal of why Ben left. I thought it was a great send off for the character. The cinematography was really great.
But the are quite a few things I didn't like. Most of the humor fell flat for me (unlike TFA where I thought most of the quips we funny). The side story with Poe, Finn and Rose was so boring to me. I felt like we built up this potential friendship with Poe and Finn and just didn't execute it. The whole Canto Bite sequence was extremely boring to me... I was asking myself when it was going to be over when I first watched it. The Chase scene was so horrible to me, had me rolling my eyes. That whole sequence felt like an hour to me. The scene with Leia using the force has me laughing. Not because she was using the force but the way it was filmed made it comical. Just straight up looked funny to me which is annoying because it should've felt dramatic. I didn't like the romance between Finn and Rose because it really paled in comparison to Finn and Rey's relationship in TFA. Just felt like a waste of time when at the time I felt Finn and Rey liked each other and that was eventually going somewhere. Oh yeah and I didn't like the cameo by Yoda... It was just odd to me that he was so light hearted. Can't really explain why that bugged me, maybe I'm over all the fan service.
After thinking about the TLJ for awhile it bothered me even more when I thought about the next movie. What was the point of killing Snoke just to subvert an expectation? It was a cool scene but I was left feeling lost about the conflict. I was very interested in the mystery of the character and now I don't think it'll be explored. I liked that Rey had to come to grips with actually not being special, but now I'm concerned this will be reversed and I prefer the prior message that we all can do great things.
There really should've been a plan. That's basic writing, you lay out a general plot before you start writing.
