My thoughts:
It seems like the Cersei story may never end. I still don't feel the show has enough time to wrap all this up the right way. I thought WWs would be a bigger part of this ep titled "Eastwatch"...nope. I still feel the show is trying to squeeze in these silly political subplots. And the fact they're dragging out Cercie's story arc to the last season is almost infuriating.
I mean, maybe. But what i got from all of this was that D&D just wants to move on. A darker explanation was that GRRM told them the ending and this is them washing their hands of it after being let down by the revelation lol
Somebody said that the political stuff was a huge part of the book series, but what i got from new GRRM interviews the last 2 books are something completely different with Stoneheart playing a MUCH larger role. He also seems to hate they cut stone heart from the show.
It's not just the politics of King's Landing but the overall setup of Westeros as devised by GRRM. The political intrigue just doesn't add up with all of the various houses swearing fealty to an indifferent ruler who has not contributed to the security or expansion of the outer kingdoms. Why any of them are loyal to the throne makes no sense from an economic, political, and aristocracy standpoint and without a driving factor like a Roman Church or a great ongoing War between two vast competing kingdoms the current political world makes no sense to me. For all the credit GRRM fans give to him for providing detail and "realism" I think they're showing their lack of historical knowledge since he borrows heavily from English and European Christian history in the Middle-Ages and subsequently the Renaissance.
"Why any of them are loyal to the throne makes no sense from an economic, political, and aristocracy standpoint and without a driving factor like a Roman Church"
They're not loyal anymore.
"It was the Dragons we bowed to... The Dragons are dead.... King in the Norfff!!!"
The dragons didn't come until Aegon, and that was only 300 years prior. And they've been dead in Westeros for only about 150 years. So, when the Greatjon says that it was the dragons they bowed to, but now the dragons are dead, he's not talking about being ignored for thousands of years. He's talking about being ignored for the past century and a half.
It's possible several of the kingdoms (but the North especially) had been harboring resentment ever since but needed the spark that would throw them into open rebellion (I would imagine executing one's liege lord after publicly promising clemency would count as a pretty big spark). Revolts can take a long time to bring to fruition, so I don't think 150 years to be a HUGELY long period of time. If it HAD been thousands of years, I might be skeptical too, but a century and a half sounds pretty reasonable to me.
