Because it shows how the prequels failed to communicate the story, and why their legacy continues to make the setting worse. This mainstream interpretation of events is directly responsible for The Last Jedi and The Acolyte and lots of other bad EU stories, and like I’ve been saying, retroactively damages the original trilogy. I think it has some real life consequences as well but I won’t get into that.
I don’t think that connects. People come out of movies all the time with different ideas. And when the movies basically put out the opposite of this for the most part, I think that’s the issue with those that interpret it that way.
A. I think TLJ had almost nothing to say about the Jedi as a whole, and just had Luke whine about how they failed mostly. Even the Acolyte’s writing is thin, to me, and it only actually directly says that a few Jedi were corrupt or messed up. Which changes nothing about the Jedi as a whole. Again, I think the responsibility of those who wrote it that way. Why would the PT be at fault for the decisions of others? Criticize the movies all you want, but the jedi’s worst trait, that I see, in the movies, at worst, is a couple having arrogance issues or apathy or lacking awareness, in regards to personality. Yeah, there’s the idea of them being lacking in competence from some (which I don’t entirely agree with), but nothing that would lend itself to anything TLJ or Acolyte may be trying to do with them (I say try because I think they’re so weak or thin they say fairly little, beyond what I said above).
B. Why does it matter that other people saw it this way to the point where they’d do these things? Why would it change the views or emotions of someone who doesn’t think that?
