I didn't say they were completely incapable of writing anything good. I like the scene where Robert and Cersei talk about their marriage, for example. I love the scene where Jaime tells Robert about the Mad King's last words.

I said that I'm not always happy with their handling of the show as a whole. The Sand Snakes, Arya getting stabbed through the guts then jumping in a disgusting sewage river and being fine after just sleeping a little while, Euron's apparent teleportation and ability to sneak up on people with a fleet of ships on the open sea—things like that.

Game of Thrones was appealing in part to me because of its absurdly extensive internal logic. George R. R. Martin treated the world as an actual place with its own economy and political systems. Even when it was unpredictable, every action had a natural, logical cause and effect.

I just don't get that kind of depth with D. B. Weiss and David Benioff. I just can't imagine the same people who wrote the Sand Snakes would be capable of properly setting up something like the Red Wedding on their own.
