My point was simply that this season was not badly written or predictable. It may not have had huge plot twists, but it still had some great surprises. And those things that were predictable such as Arya, had the same set up in the books. Like now that we know Lyanna is Jons mom, I don't see people bemoaning how predictable Martin's writing was. Just the show.
