A lot of Luke’s motivations were solidified by the conversation where he uses Sidious’ name: and describes the plot of the prequels. Abrams did everything he could to ignore as much of the saga as he could. He remade A New Hope, gave some nostalgia, didn’t complete any character arcs, then four years later strings together something that references his movie and a scene from RotS. He prioritised looks over story at every turn, and the films are so shallow because of it. Johnson told a story, even if people didn’t like the story he told. There are layers and connections to evolving the saga as a whole.
