You could be critical of the NK here and say he paid the price for standing down his army so that he could be the one to kill the Raven, all eyes were focused on Bran and NK because the NK believed it was safe, and someone quick and stealthy got in there.
That's kind of the standard thing for unstoppable villains, yeah: their own hubris brings them down. Even though it rings true, I tend to think it's kind of lame and cliche now, unless they find a clever way to have it manifest beyond just "I'm so confident I'm going to make myself unnecessarily vulnerable just because." More interesting if their hubris brings them down more indirectly.
But honestly, all the above is how I feel about
human villains. For someone who's being portrayed as cold (heh) and calculating and emotionless and hell-bent on destruction, it seems ridiculous that they'd be brought down by being
haughty. Especially when it hasn't even really been established what they think or why they do what they do, exactly. Their powers and motivations and all that have been pretty murky, save for a couple of offhand comments in the last couple of episodes.
Put another way: if the Night King is just a thoughtless force, fair enough, but then it can't be brought down by hubris. And if he's an actual character, then they need to treat him like one and actually flesh (heh again) him out a bit.
I'm still sceptical of how Arya could get so close though, the last few steps, its believable that she can get to within a few metres of it but that final leap, I'm not sure, but again if everyone's still and distracted someone quick could dart in there.
Yeah, same. And I dunno what she even jumped off of. There's just so many cool ways to have done it! Secret passages only she knows about, wight face-stealing. There's all this low-hanging fruit there about ways to make this cooler
and make more sense.
I also thought when she was in the Castle she might be able to take a dead face, I actually think that would have been a better way. They are probably saving the face changing for something later and don't want to have 2 similar endings.
Yeah, I'll have complaints either way, but I
really hope they use that later. I'm not sure how they would now since the threat has been dealt with. I guess just to freak someone out, but my guess is we won't get it at all.
It's quite possible we'll all be saying this should have been the case. I'm also really interested to see if the NK goes down like this in the books (sometime in the 2030's at this rate).
Gotta imagine something a lot more interesting and nuanced will happen in the books.
