I loved how we started in the hot lands of Mereen, stopped in the Spring/Autumn feel of King's Landing and then ended at the most northern and coldest land ever shown in the series. Even the Littlefinger/Sansa bit fits since they are on the water and there's a ocean separating Essos from Westeros. Brilliant stuff.
The acting was so good too, except for that bit in Craster's, that didn't really look like a drunken fit. You can tell so much just by paying attention to Margeary's, Jamie's or Littlefinger's eyes.
And seeing that row of White Walkers was intimidating, could they all be Craster's sons? I was half expecting a "brotherrr....." line in that last scene haha.
