Five seconds of research later...
Yup, you're right. This is the worst movie.
Yes, I honestly think the inclusion of either Shriv or Kalani may have saved this movie for me.
That's not quite I interpreted. One of the last things said in that conversation is, "You're just a child with a mask," or something along those lines. In anger, Kylo destroys his helmet, hoping that this would be a metaphorical transformation for him. Apparently, that transformation lasted 4/5 of a film before he just fixed it.
I don't think that's using nostalgia, that's filling in more to the story. The OT left plenty of room for a prequel trilogy to begin (Anakin Skywalker, the mention of Luke and Leia's mother, Obi-Wan Kenobi, they even mentioned the Clone Wars)
I can see this, but the rest:
Except for maybe the whole C-3PO part, it all was pretty integral to the plot. It's believable. Yoda was a great Jedi Master who mentored Obi-Wan, of course he would be there. The films lead up to the OT, of course we're going to see how twin children end up not on different planets without knowing how the other exists.
This isn't exactly fair. It was an apparent major piece to the world of Star Wars, and Lucas decided, "let's make some films about Anakin, during the Clone Wars." There isn't any nostalgia or fan service in that, that is simply expanding on the story. Just because it was mentioned before doesn't mean that it being shown is a fan service or use of nostalgia. Those are integral parts of the film because they are built around that simple idea. Nobody cares about going to see the Prequels because that one line by Ben Kenobi was a great part of their childhood, they want to see it because it's Star Wars and they want to know what happened in the universe.
I know my argument is very unclear, but it's also very hard to describe. I just see the Sequels utilizing the fans' nostalgia in a way that seems to try to cover up the fact that they are not that great, while the Prequels, if at all, use nostalgia because that's their story. (I still am highly disturbed that C-3PO and R2's only absence from a film is Solo)
That's how the story goes, the Geonosians designed the early stages of the Death Star.
We need to understand why Luke has an Uncle and yet Anakin is an only child. Imagine if he wasn't in there, people would be able to write off the Prequels as not being canon (if they hadn't already) because Luke should never have had an uncle. But since Shmi married Owen's father, we see that Luke has more of a step-uncle.
Your arguments aren't invalid, and there is a solid case that Prequels used nostalgia, but I see the Sequels use it more of a crutch than that extra seasoning on top. I think the #1 rule in all of storytelling, and I think many will agree with me (for once) here, is that you need to have a story first. Make it a good one, or else everything you add will be trying to compensate for it. Nostalgia and fan service is fine, as long as it isn't used as a foundation and more as a support. Rise of Skywalker tried to take Endgame, flavor it Star Wars, and check off every piece of Star Wars movie must-have in, what? Two hours? Honestly, I think this movie could have been much better if all they did was add on another hour. Maybe an intermission, as I could see that fitting better in Star Wars than in Marvel.
