Imagine with me, if you will, a different Return of the Jedi. The primary protagonist/antagonist conflict is not with Luke and Palpatine, it’s with Luke and Vader. And yet they don’t spend a heck of a lot of time onscreen together. It’s only near the end of the second act and into the third that they finally confront each other. Can you imagine what it would have been like if they encountered each other multiple times throughout the movie? Like, for example, if he got word that Luke was back on Tatooine, and headed out there?
Now, contrast that with The Rise of Skywalker. Again, Rey/Palpatine isn’t the real conflict here, it’s Rey/Kylo. And their issues get a lot more attention… Punch it!
