I've read through about half the thread but I'll go ahead and give feedback...which is something that I rarely do.
I consider both KOTFE and KOTET to be a failure from a writer's perspective. Up until this point, the focus of the story has been on the player character. Once we reach the beginning of KOTFE, the focus of the story shifts away from the player character: in effect they become a bystander rather than the focus. Many of the criticisms about the expansions boil down to this, the player becomes an observer in someone else's story...and one with questionable writing to boot.
Unlike previously, the character has no say and nothing they do matters.
