Overall, I give this episode an A for the actions scenes, an F for the logic.
A few thoughts, though my biggest one revolves around the growing momentum that Bran and The Night King might be one and the same: Is there any chance that The Night King wanted all of this to go down so he could gain access to a dragon? Was all the time spent waiting behind the Wall just a feint to get them to come to him? It sure seems like he was ready with those spears and those chains for the right opportunity. Maybe he wanted Gendry to get away, warn Dany and bring the dragons to him. If so, how could he have known that would happen and that they'd come? Maybe if he was somehow ACTUALLY a mystical being of infinite time and space? That would at least make somewhat more sense then the Night King just being a crack shot.
I admit, I am STUNNED that only one of the Snow Team 7 character ended up dying and of all things, he FROZE to death! That might be the biggest twist in the episode.
The Benjen appearance felt very, very wrong. After Jon literally has been searching and wondering about him for 7 seasons, he just appears, says "Run!" and then is presumably "killed?" (Can he even be killed?). I'm assuming they didn't have time and/or wanted to just leave the details for the books..... haha, if they ever come out.
The logistics have already been mentioned, but it does seem really odd that Sansa and Winterfell are an afterthought in all this. Jon found out that Arya and Bran are alive and he doesn't even send them a note?
Finally, if Arya can't see through a note that Robb and company dismissed way back in Season 1, I think she needs to go back into training. That whole plotline feels like they are just looking for ways to mark time until the Stark girls kill Littlefinger.
If the show is trying to just clear the board for the big ending, I'd have hoped it could be done a bit more elegantly but it is what it is. TV isn't always meant for long-form fantasy storytelling, especially when budgets and contracts come into play. Still, if they manage to surprise and thrill us, I think it will ultimately be a job well done. It very well have lost some luster from its earlier heights but the show is still brilliantly and technically made.
Take care all.
