I have not seen rise of skywalker yet, seeing it on Saturday. The criticism of this film so far seems to be about fan service, messy plot and most importantly, trying to correct on the wrongs of last Jedi.
If You were JJ Abrams and his writers what would you have done going into Rise of Skywalker? Would you try to improve on the plot points of last Jedi, or ignore and retcon everything in last Jedi and come up with a total different plot points.
