Problem was people had question marks about the characters after TFA.
People had questions they needed answered with regard to character development.
TLJ ignored character-building and just bum-rushed a storyline that was taking place within a 14h window immediately after TFA. It was the ultimate franchise killer for that reason.
There was no room for anything to grow, no opera, no epic-- when your entire storyline is an episode of a TV serial. The events of TLJ took place within the same day. This is Star Wars, its supposed to have a few small time jumps and a feeling of a greater universe, a space opera.
Rian took the space opera out of Star Wars, and made a generic woke scifi blockbuster movie.
