Interesting.... We don't get the "behind the throne" stuff with the directors talking about the episodes either.
and I just watched an youtube video explaining why GOT season finale was that way, and they claim it's all predictive programing...wow! I like conspiracy theories, but this idea is crazy!
Now that I've had a chance to read some articles and think about this episode, I'm satisfied with the way it all turned out. I would have liked a few more episodes to build up and develop to that ending, but c'est la vie.
