Just to circle back on this bit. Obviously no one's mind is going to be changed at this point but I disagree that the reasons you state (same stories repeated with new characters/same ending to it all) automatically makes the ST pointless. Lots of very celebrated sequels do just that in fact, whether it be James Bond, Indiana Jones, Mad Max, Star Wars, ALIEN/ALIENS, MCU or many others. Sometimes it's all about the fun of hopping on that merry-go-round again.
And I actually do think that the overall narrative had a valid enough point just for the simple reason that it addressed previously open threads from the PT and OT that were never really followed through on. "Cheating death," "unlimited power," "luminous beings who use the Force for knowledge and defense, never for attack" and "the ability to destroy a planet is insignificant compared to the Power of the Force" to name some of the big ones. All of those manifested for the first times in the Saga. Even Yoda advising Luke in ESB that "once you go start down the quick and easy path forever will it dominate your destiny." TLJ showed that no matter how powerful Luke got Yoda's warning held true compared to ROTJ which implied that Luke had permanently leveled up and would never struggle with any repercussions to his mistakes ever again.
Also the super annoying continuity error of Leia being the "other" and somehow being the new last hope if Luke failed to rescue her, even though him failing by definition meant that she'd die too. The ST allows for the (IMO) satisfying retcon that Yoda was looking ahead to Rey and not Leia which as has been discussed before is closer to what they were going for when writing the script for ESB anyway.
Plus the galaxy did end in a different place than where it was at the end of the OT since it was no longer dependent on a centralized Republic, Resistance or Rebellion to defend them from military tyranny. For the first time ever the common people of the galaxy united and learned that they could easily far outnumber, and defeat, any new such threat that might arise again. It really did allow for a definitive end so to speak to the "star wars."
Again I know that no one's mind will be changed but just thought I'd weigh in for the fun of it anyway.
