The lack of cohesion between the two movies has become a bit of a problem to me. It’s clear that the movies don’t know where they’re going. Plotlines are set up in TFA that are completely abandoned in TLJ, or just subverted in the laziest way. I do like the idea that Rey’s parents are nobodies, but it just doesn’t fit with what we were shown in TFA. This cohesion problem isn’t exclusive to the ST, it’s prominent in the OT as well; I suppose it just never bothered me since I grew up with the trilogy already existing. Leia was always Luke’s sister, in my mind.
