I didn't think the episode was that bad. They had to have something like this to take into account traveling time and making dragonglass weapons, etc. Kinda made sense to have a no action episode to start the season.
Can't wait to see the funny things people make about the scene when Jon is kissing Daenerys while looking over her shoulder right into Drogon's face.
Who is going to be the target of the special weapon Arya asked Gendry to make that has a dragonglass tip?
--The Night King?
--Random White Walker?
There was a serious lack of Dothraki in this episode and I was wondering how effective they can be in the fight ahead. Its a TV show, I know, but for the sake of discussion. Most cold areas of the world (in ancient times) were wild, rough and untamed lands with uneven ground and lots of obstacles like forests and rocky terrain. That type of environment is less than ideal for large scale horse combat. There may be some areas where limited cavalry will work (like when Stannis's army got destroyed) but all in all the Dothraki are a "horde" of horses. They excel on large flat ground which they are not going to find up north. I am interested to see how the Dothraki play it into the battles ahead.
