If the resolution to the series is Danaerys (and her mostly shitty plotlines/acting both in the book and the show) showing up to Westeros and uniting the realm record time. The Realm that actively fought to not stay united through intricate plots, politics, deceit, war and character development. Have them bend the knee then wait around until they hear that the Others are actually serious business then tramp up North and squash it all within 5 episodes. I mean fuck, even during the Aegon Conquest Dorne told him to fuck off dragons and all. The idea that everyone agrees to unite with Dany in a moment's notice goes against everything the series has ever done. But there doesn't seem to be a way to avoid NOT doing that.
That will be some of the shittiest troll writing of all time.
