One fault of ROTS is that it basically tells us “nothing interesting happened for 20 years after this movie” and you suggest they should have done the same for episode 7? No thanks.
I disagree. I don’t think we need important things happening all the time. The natural progression post-RotJ in my view would be the eventual rise of the republic and the training of a new reformed Jedi Order that has almost nothing to do with the PT-Jedi Order because Luke is nothing like them. Apparently the latter didn’t happen, but the Republic thing did. But that’s not really exciting, and is nothing unexpected that would need to be documetned.
But there was this crazy thing in the Jedi temple where Kylo Ren killed everyone. There was turmoil in the republic and Leia going rogue and forming a resistance. The weak remnants of the Empire growing super strong. So that are things that if you just tell me that they happen I won’t really believe it.
My argument will eventually go back to the FO and Snoke being severely underdeveloped, combining it with the 3 flashbacks trying to sell me that Luke would almost kill his nephew. No thanks.
