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.
But what does that have to do with Palpatine’s name? You implied that using Sidious is somehow an indicator that Rian cared about his story, and that using Palpatine is somehow an indication that JJ didn’t care about telling a good story. I don’t really understand how that makes sense.
Also, TFA isn’t a remake of ANH. I have no idea how that idea became so common. Besides a few surface-level callbacks, the movies are nothing alike. And I don’t think that not resolving character arcs in TFA should be considered a criticism, given that it was intended to be the first installment of a trilogy.
