Slow first episode, but expected. I'm glad they didn't take time to catch up on EVERY character - we would have really gotten nowhere, like in Season 2's premiere. I much preferred the extra breathing room we got this time.
Anyway the real fun starts next Sunday: Jaime + Brienne, Arya, and more Dany I hope. Her storyline kicks ass this season. Mmmm those Unsullied.
My pick for best scene of the episode by far was: Tywin and Tyrion. I think Charles Dance might be the best casting decision of the series; his contempt was dripping from every word. I cringed.
