I thought the Dothraki scene was better than in the books, but I missed the struggling in "Dragonstone" issue, which D&D could've played with for 4 episodes next season. Unfortunately if the 7-only season idea is real, that wasn't a possibility.
Expectations required a 3-hour finale. I'm actually glad the WoS got the gravity and length it deserved. I'm also glad the episode only focused on 6-8 of the 45 things we were expecting.
