I liked the episode, but I was kind of expecting more in kicking off the final season. I don't want to complain because I love the show but when there are only six episodes left, to see them burn an entire episode with all these long-awaited family/friend/frenemy reunions was a little anti-climatic.
I was glad Jon finally learned who he really was but man they took their time getting to that point having Bran see Jon without telling him/everyone and then having Sam meet Dany first before going to Jon finally.
At least Dondarrion got to set an undead kid stuck to a wall on fire so some action happened.

Maybe next week will be the start of ****-hits-the-fan with the undead army reaching Winterfell...
