My hope is that whatever the Thrones guys are doing for Star Wars is an adaptation of something that already exists. That or the Disney people keep their leash short. They were fine, even good, at adapting the books in the first couple seasons, so hopefully if someone else created the story and they're just adapting it, they'll do ok.
At this point it's pretty clear they aren't going to stick the landing. I just hope the characters I like, Davos and the Starks and Brienne, get good endings. Or at least aren't idiots this final episode.
