I agree. I guess there could be more of the books completed now than two or three years ago. I wrote my post before seeing yesterday’s/today’s episode, which I have now seen and thought was actually a step up again. I’d expect the main thing that happens in this episode to also happen in the upcoming books, I do believe GRRM had already layed out plot points that huge.
And indeed, this season, and probably the previous as well should’ve been a full 10 episodes.
Yeah, I'm also not surprised at what happened, but more concerned of how it happened. More episodes could have definitely set it up better.
