Fuck. Wow. That episode was incredible. They stuffed a TON of plot developments into this and every one of them left me grinning (well, except the end of Margarey, r.i.p.). Some long overdue and satisfying conclusions, one long-time theory confirmed, and all of it pretty perfectly woven into the aftermath of the last couple episodes at the same time. The balancing act of characters and subplots tonight was just really well done.
Miguel Sapochnik directed the hell out of this; I think, in some respects, it's an even more impressively made episode than Battle of the Bastards. I hope Benioff and Weiss have dug some contractual claws into him for the next two years so that he can deliver a couple more amazing hours for the show like these two and Hardhome.
Best episode of the season, best finale of the entire show, and I'm tempted to think S6 was the best overall season. I had nowhere near the antipathy toward S5 that most of you seemed to have, I liked it for the most part, but it was one of the weaker years of the show for me. This season was a huge rebound. And now the wait begins again.
