I don't know, this season kind of feels the same to the previous ones to me. GRRM is the king of letting you hang. Sets up Bran to become a Gandalf type character, doesn't do it. Kill off other characters he shouldn't have, resurrects them. Also any reading the books will realise how late he actually introduces the idea of Aegon Targaryan (book 4), after he said publicly it would be a trilogy. Personally I just think he is a crappy author. People always told me that that makes him different from other fantasy authors, because he doesn't play by the rules. Hence no morally sound characters etc.
Well to everyone that said that, I hope you are satisfied now.
Edit:
Sorry didn't see Ron's post above. Yeah, exactly that. GRRM is a great pantser. Been saying it all along. All the greats, Tolkien, Gemmell, great plotters. Robert Jordan is also a pantser, hence why he died before actually finishing Wheel of Time. I have a very strong preference for reading/watching plotters rather than pantsers.
This is exactly why he introduces things he never properly develops. Or why Jon Snow traveled the entire Seven Kingdoms three times over while the Night King's Army moved 5km's (and they were introduced right at the start only to be ignored for 3 books). Pantsers should actually be known as "plot-holers".
