There’s a few questions I think are lacking some true facts options:
Somehow, Palpatine returned. How though?
It really depends on the goal of the fanedit. There are plenty of hypothetical fanedits where cutting him out would work, and some fanedits where he’d have to be there. I don’t think, in a fanediting sense, there is a correct or incorrect answer.
Why is Rey so powerful?
The Force is a spiritual concept and you get powerful in the Force through the right mindset. It’s not like a workout regimen. For example, all of Luke’s training in the Original Trilogy is mental exercises. All of it. Rey starts out TFA sort of where Luke is in the middle of ESB, mind-set wise. I mean, it takes most of ANH before Luke even believes the Force exists, until the end of the movie until he has any sort of faith in it, and until the end of ESB until he has to rely on it. Rey starts out TFA already believing the legends of the Jedi and the Rebellion and yaddah yaddah yaddah, basically putting her where Luke is. However, this also means she has some stupid ideas about the Force, which she starts to get wringed out of her in TLJ (although this isn’t followed through in TRoS).
Beyond that, she’s not really exceptionally powerful.
Which force ghosts (or other people) does Rey see at the end when she’s asked 'Rey who?'
I’d cut that interaction out entirely, or at the very least cut that aspect out.
Palpatine has been “every voice in Kylo’s head”?
I’d also cut that out. It doesn’t really go anywhere, which sucks because I was pumped when that line was in the trailer.
Should the concept of Force Teleport-a-lightsaber-to-your-friend be introduced to allow Rey to teleport her lightsaber to Kylo?
The Last Jedi implies that it’s not a completely unique thing for two people to be Force Skyping. It’s novel enough that Kylo is confused about it, but not novel enough that he’s completely bewildered. He works some stuff out. It doesn’t necessarily have to be a dyad thing.
Palpatine can force lightning a whole fleet?
Can or should? I think he can but I don’t think he should. Kind of makes that happy victory scene a lot more sour.
The final resting place of the Second Death Star doesn’t look much like the forest moon of Endor, does it?
The first answer kind of makes the second answer objectively wrong. The question probably should be more about whether it should be Endor, not whether it is Endor.
Rey “kills” Chewie with lightning!
Probably the most common opinion on this one is that she should still think she killed Chewie, but we don’t learn that isn’t true until she does too. Weird that’s not an option.
Leia dies to distract Kylo Ren so Rey can stab him!
What I thought happened was that Rey killed Leia. Were I to make a fanedit of TRoS, I’d do that.
Kylo has a memory of Han Solo which encourages him to reclaim his identity as Ben Solo?
I want to make Han an actual Force Ghost. I don’t give a damn that it contradicts the prequels.
Rey builds a gold lightsaber for herself at the end!
Green god damn it
