GoT Episode 3.... The Long Night.
Wow!
*MASSIVE HUGE ULTRA SPOILER ALERT***********
Phenomenal, absolutely phenomenal.
...That said:
1. I thought the battle tactics were stupid. The way the Dothraki died was chillingly cool but the tactic of wasting the, previously mentioned, unbeatable fighting force of the known world in an open field, was daft.
2. Death of the Night King by flying teenager seemed slightly unrealistic. I think Arya is utterly awesome but it just seemed a bit too random how it happened.
3. I never thought I'd accuse GoT of this but the main character casualty count actually seemed unrealistically low given the circumstances!
Still, what a show, can't wait for the rest.
