I always stick to the old Godard quote; “it’s not about where you take it from, but where you take it to.” And ANH borrowing ideas from everything from Kurosawa, to Flash Gordon is great because Lucas took old tropes and concepts and made something new from it. However, when it’s SW reusing exact plot points from SW then it’s different. It doesn’t necessarily make it bad, but it’s very different. F.ex. (SORT-OF SPOILERS) I thought that Rey was a very good re-imagining of Luke in ANH because it took it somewhere new. Starkiller on the other hand didn’t really add anything new of any plot value. I don’t dislike it, but I can’t call I brilliant. It works, but it works in a very different kind of way.
