Glad you like it! Yes the netherworld was the big nostalgiafest that everyone wanted, but after I got to thinking about it, the scene had a lot of potential to drive the story forward as well as fill out Ben’s backstory.
Kylo losing his power definitely started out as an idea to quickly nerf his level to keep our heroes from becoming overpowered in relation to the villains, but again it feels right as a reaction to such an extreme alignment shift. I don’t think it will be permanent, but his regaining power must be for very good reasons…
As for it being more booklike, that’s just how I’m comfortable writing. Screenplays always feel awkward to read compared to novels and if there’s no chance of it getting made, why go through the trouble?
