On the other hand, to me the whole trilogy has been about how there’s no way to definitively end tyranny, and how the dark side will always come back and you have to be prepared to stop it even in the face of knowing stopping it might not be permanent. To that end, I’ll be kinda upset if they “definitively” end the war, as I don’t think that’s be a very satisfying end to this story.
I think a good story should have a beginning and an end. A new story can unfold, but imo it should not be about Empire vs rebels, or a Jedi apprentice betraying his or her master. Been there, done that…twice… If you can’t tell an original story with new characters, who are put in new situations, better not tell a story at all, I think, or risk turning the franchise into a cliché. To paraphrase Bilbo Baggins, the Skywalker Saga already feels like butter scraped over too much bread for me.
To me, you can end a story without having a definitive end to everything going on. A lot of great, conclusive endings still have some elements of ambiguity and suggestion that things will continue beyond the final page. Star Wars hasn’t been a true fairytale since at least 1980, so I don’t think a perfect little all encompassing ending with a bow and cherry on top is fitting, especially after the last two episodes. Hell, even the original film still had Vader getting away as the heroes celebrated. It’s part of the serial tradition.
Personally I’d be disappointed if we get a definitive ending to the conflict, but I’d be equally disappointed if we got an Episode X somewhere down the line (for fear of what is there left to say?). I’d rather imagine the episodes continue but we don’t see them, because the saga’s story has been fully told.
