I recommend these videos as they touch on the subject of the poetry angle to a degree.
It’s more than a repetitive device. It’s about creating links between the two trilogies of two different generations of people and a family. They’re one of the same yet different from each other. The Original Trilogy on its own really follows the trajectory. Mind you it’s to a lesser extent but it’s there. The trilogy has lots of parallels within its own narrative. IV and VI correlate in certain ways. Just as V and VI do. The Prequels do it within their own narrative as well. It’s not about copying but creating moments that are poetic yet different from each other. Just like written poetry. The Sequels tried but ended up copying and pasting a lot of the time. The Last Jedi I find gets closest to getting it right in connecting the whole saga together. It doesn’t fully but it does succeed at times.
I’d prefer the final word in the Skywalker saga being George’s vision and having what comes after it beginning the process of creating something new and more experimental. It can mix it up and go in different directions as it’s not beholden to the established rules of the saga films. I would have welcomed new takes and spins with open arms as the story that was intended as a nine part saga was completed as the original author intended.
It honestly doesn’t bother me when creators of work go in a different direction than that of what fans want. They’re not there to please us. It’s when someone else has a responsibility to continue a story that I have a problem. It’s the difference between one vision and that of a corporation in a way. One does it for the joy of telling their own tale, while the other does it to max out on profits.
I wish I had more of a favourable view of the Sequels like you do. The only time I find I do is when I see them as disconnected from George’s story. As their own thing they are pretty enjoyable popcorn flicks but as a conclusion to what he started I find they don’t work for me. Star Wars was always a collection of art films with aspects of popcorn flicks to entertain. I find they’re now just the latter and nothing more.
