Yeah Luke and Leia being related is one of the retcons that irritates me the most.
While the fact that Rey’s origin kept changing throughout production is weird, I find it funny that most people in the reddit/YouTube sphere seem to be ignoring the fact that all of starwars has practically been BUILT on retcons and the idea of “making it up as you go along.”
One can’t help but wonder what the fandom would be like now had we gotten Splinter instead of Empire as the sequel to Star Wars. Sure, maybe there wouldn’t be as much fans or as much passion, and maybe the movies wouldn’t feel as “grand” as they do now, but it sounds like things wouldn’t have been so “retconny” had the series stuck more closely to its “pulp serial” roots.
