JJ's whole plan was to redo the original trilogy with cameos.

Rating: 1/10 (23 December 2019)

But Rian killed off Snoke so JJ had to either set up a new big bad or bring back an old established one.
Some people are saying don't listen to the reviews just go see it for yourself. That is awful consumer advice. Sure, if you're still invested in this franchise after the previous films go get closure. But if you're undecided don't reward Disney for lazy, predatory practices. Or do. Perhaps if they get sloppy other studios will get a larger share of the box office and we won't have to suffer through endless paint by numbers Superhero Movies and Live Action Reboots. Nostalgia is a disease, we must create new things.
