I liked how thorough the prequels were about the politics, but the directive for the new trilogy was to nuke political content from orbit because of how it was received in the prequels.The prequels sort of had this weird effect of making people expect these films to be Wikipedia articles. The OT didn’t dwell much at all a the political state of the galaxy or the histories of its various characters. Look how little the function of the senate and it being removed was talked about in ANH.
The prequels deep diving the history of every main OT character and explaining the political function of the government is not the norm.
We don’t need the film to stop and explain the relationship of the Resistance and the Republic in detail because everything we need to know is on screen. Republic = peaceful government of the galaxy. Resistance = independent force with backing of the Republic. There you are good to go, and we get that info in the crawl.
