Well I thought it was rather marvelous

A battle at night in the north with added snowstorm : just as I'd imagined really
Claustrophobic battle scenes, dance of the dragons, some pretty cool blood and gut deaths and that annoying little Mormont girl died AND got turned

The Dothraki charge was brilliantly done - atmospheric and such a hard hitting moment, far better than showing close up fighting as there was so much of that still to come.
Sam - so many fine fine qualities but fighting in a battle really isn't one of them

Mind you was nice for setting up Edds death.
Beric - gone but that voice not forgotten.
Melisandra - she had to turn up sooner or later and I think it closed her character arc rather well.
Theon - had to happen and rather touching I thought.
Bran - really what is the point? I assume the "I have to go now" stuff will be explained and there will be a reason behind it (and him) but at the moment all a bit nothing really.
Night King - not such a hard ass after all

And killed in a distinct echo of his creation

Arya - Yay

go girl

Actually long foreshadowed in hindsight and I thought the episode was excellent for her showing both the deadly killer side and the still vulnerable young woman.
Many other bits in the episode that a rewatch at some point is in order. As to what now well there can't be much of an army left so some political shenanigans to come no doubt
