Nah, it really isn’t that complex. I summarize it in a single sentence in my last draft: “The Emperor manipulated the Force itself into creating life.” The reason it works so well is because it relies on lore and storylines already established in the prequels.
I mean, it kinda still is complex?
I was going over these ideas with my girlfriend the other day, and told her the one about Palpatine creating Rey through the Force like he created Anakin, and she was just like, “Huh?” She genuinely didn’t know or remember that Palpatine was in any way involved in Anakin’s creation. And this is someone who has watched all of the movies and even read some prequel novels.
I don’t think we can just assume that the average person watching these movies would be knowledgeable about the contested lore surrounding a movie that came out almost twenty years ago. Maybe people on these forums or who watch fanedits of these movies would know, but for the average Joe, I very much doubt it.
All this is to say that all the ideas we like right now are a tougher sell to the average moviegoer than ‘Rey was Palpatine’s granddaughter’, and that’s just something we have to accept and work with.
