I agree with what most people have been saying.
The stuff past the wall didn't actually bother me that much. We have had 4 battle scenes in 6 episodes and this was at least better than the pirates of the carribean scene so third isn't bad. I was fine with the wights waiting because I think he knew the dragons were coming, we have scene the night king call hordes of wights to fall off a cliff only to raise them again and screw with jons head. The worst part of thatnwhole scene was benjin coming out of nowhere rhegon totally should have circled back, and laid down a line of fire while Jon hopped on his back.
Now for my real issue, winterfell. All that needs to be done is describe to someone the three stark siblings as children, briefly explain what tragedy occurred to their parents and brothers, then explain the journey each has gone on. Finally tell the person these siblings have been reunited all returning to their home where they grew up. That person will respond oh man that must be amazing, I would hate to be anyone that isn't 100% on the starks good side because those kids must be on top of everything. Remember Bran sees everything, Sansa has the entire north supporting her, and arya is the deadliest fighter in westeros. Essentially they all suffered because of the family and safety they lost but they haven't forma second discussed that. Like arya and Sansa should totally be arguing over who murdered their enemies in a cooler way. Arya's all "remember the man who killed rob and mother, I fed his children to him in a pie then slit his throat", Sansa's all "pity you fed his children to him, I fed the man who killed rickon to his children...his children were starving savage dogs." Meanwhile Bran's all "you girls are kinda crazy...oh and the guy who basically killed father is downstairs. Let's invite him for a meeting in the ravens room and I'll warg into all of them and peck his eyes out!" End of scene and all threats to the glorious all powerful stark house.
