Then again, maybe it'll be fine because all the source material is finished and they don't have to fail at writing the end of the story on their own.
I was already somewhat sceptical as I heard that the story is being moved to the U.S. which seemed odd, but it was apparently signed off by Liu Cixin.
I'm still a bit in shock as to how bad GoT season 8 was. So many plotlines and character development were just shredded, burnt and then thrown away. And that battle looked impressive on-screen (if you like watching a black screen with little points of light) but just made absolutely no sense tactically.
