I smiled at the references to the name of GRRM's most recent book. A good bit of marketing there. Props to D&D for plugging GRRM's book.
I was pretty shocked that they actually did kill off Shireen. GRRM is knew this was coming, and really brings attention to his comment that D&D are even worse than him when it comes to killing off characters. Considering they did something so shocking, I would have liked to see the effect of it in the same episode, or the spell she casts because of it, because now I'm sitting here feeling they killed her off unnecessarily and for shock value alone.
Usually episode 9 is the big epic battle scene of the story. Overall I enjoyed the episode, but felt episode 8's end scene was the epic scene of the season. The fighting pits, even with drogon, which was cool, still doesn't match up to the battle with the wights, and the ominous dread of seeing the white walkers standing at the shoreline, bringing the wildlings they'd just killed back to life.
