Well, maybe not. The Last Jedi was anti-nostalgia, I felt, and a lot of people hated it (I love it for the same reason). The reason I beleve Rise of the Skywalker was so bad was because they tried to un-do all the things the previous movie set up to try to address criticism, instead of going with what they were given.
The whole 'Somehow Palpatine returned' nonsense could easily be solved by continuing Kylo Ren's trajectory towards being the big bad and making him irredeemable. But instead, Abrahams wanted to re-thread Return of the Jedi and have Ren be the Vader of the trilogy and have his redemption arc of someone who was simply misguided by an evil master. And also somehow make Rey be related to characters of the past instead of a nobody, which I thought was more interesting.
