I watched the episode again yesterday. My initial viewing was too emotional to make a decent judgement of everything but having had a chance to see it again I have to say that I agree with the majority of complaints.
The plot armour for some of these characters was ridiculous. Brienne, Podraig, Davos, Greyworm and Missandei should have all been killed off. I can only assume we have another epic battle left (Emilia Clarke hinted towards 5 being that) that will finish some of these characters off because otherwise it's ridiculously watered down.
I loved the final sequence with the night king walking towards Bran. The score made it; what an absolutely fantastic piece of music that was. That being said, his death did a great disservice to him. The night king should have been so much more and Jon should have been there to at least fight him somewhat.
There's part of me that hopes the night king isn't gone, but considering how dumbed down this show became (still highly entertaining) after they past the books, I don't have high hopes
