Well, this episode was glorious.
I definitely enjoyed watching the Wild Fire vaporize everybody the most.
I also thoroughly enjoyed the producers utilizing Lord Manderly's meat-pie mini-storyline from the books by giving it to Arya. Beautiful.
Cersei, enjoy your throne while you can, you have earned it
Also, I simply cannot help but HATE everything about Dorne and the sandsnakes, so Olenna verbally lashing them all was a much appreciated touch.
