I'll just be honest: I have problems with a lot of decisions Georgey has made as a writer, including the whole "let's write from 16^23 perspectives with characters we'll try to kill off and make a really confusing world for everyone!" I don't think it's a good approach. I also don't like how we hop between different continents so frequently. Frankly, there should be a book about the war in the north, another book with a southern perspective, another book about shit happening around the wall, and a book about what's happening with those goddamned dragons, and maybe one last book to FINALLY TIE IT TOGETHER and make a complete story from a limited number of perspectives.
But instead we're led on an infinite goose chase about coming dragons interspersed with tales of non-consensual sex of varying degrees of "oh God why am I reading this?"
EDIT: Let me add this: GRRM does a wonderful job in his story about Duncan the Tall or whatever his name is. It's focused around one character - an actual protagonist and idealistic young knight (who's actually a peasant IIRC) who's living in a truly crapsack world. It doesn't harm GRRM's ability to write about how crapsack the world is, and it still breaks many fantasy norms. It's way better than his shit in the main series of books.
He can write when he actually wants to, but I think he just knows what sells and says "eh, why the fuck not?"
