It has been pretty well established that Return of the Jedi sucked, so, from a blank slate, how would you write it?
I am envisioning a situation where Jabba the Hutt and Bobba Fett play more significant roles. As in, Jabba becomes angry with the Empire and tries to use Han Solo as some sort of leverage against it, while also being in opposition to the rebel alliance. At some point, Luke finds himself in a struggle with Bobba Fett, who delivers Luke to the Emperor on whatever planet he is on. In the confrontation, Luke kills the Emperor and Darth Vader flees yet again, perhaps pursued by the bounty hunter.
Now Luke reunites with Leia, who is trying to work a deal with Jabba to free Han Solo. But Luke is conflicted because he has been to the dark side and has moments when he loses self-control. In a fit of rage, he attacks Jabba’s compound, frees Han, and kills a lot of people (but probably not Jabba). Terrified of what he has become, he goes to Dagoba to get help from Yoda, who does all he can, but the effort costs him his life.
Imperial warships appear over the planet because Darth Vader has figured out where Luke went. Chase scene (Vader wants Luke, either alive or dead) that develops into a battle scene, with forces loyal to Jabba shooting at everyone, Vader is captured by Bobba Fett because he could not force himself to kill Luke, but Han Solo destroys Fett’s ship because no one deserves to be tortured by Jabba the Hutt.
Leia helps Luke avoid the descent into darkness, but he remains conflicted, so she and Han fly him to back Dagoba where he will live out his life amongst Yoda’s people (the reptile equivalent of teddy-bears).
Not very well thought out, but potentially more interesting, I think.
