Good point, and I see your argument. Just to clarify: When I discribed the NK as purely evil, I'm basing this on what Bran said--that he intends and wants to destroy all of humanity. Perhaps Bran is wrong, and given that he has been wrong before (i.e., calling Jon a Sand), he could very have been wrong about the NK's intentions. If it comes out in the remaining episodes that he was more nuanced and 'grey' than that, then my objection will no longer hold any weight. As of right now, with the way the NK was portrayed in the show, he is purely evil. If it remains this way, then my objection that D&D departed from Martin's outlook stands. I recognize that the NK had no choice, but I'm not sure how he could justify wanting to destroy those who did not do this to him (if that was his intention).
Ah, I see what you mean. Thanks for taking the time to explain.
Oh, indeed--LOTR and GoT are different. I was only responding to your comment that the destruction of the ring at Mount Doom and the death of the NK were somewhat analogous. They are but only to an extent, as you've discussed here. You've made some excellent points here about the struggle, so to be fair, I will need to take what you've said into consideration and change my opinion if it's ultimately persuasive. Again, thanks for the thoughtful, respectful discussion.
I'm not trying to be negative just to be critical, so I hope it doesn't come across that way. I'm in graduate school, so I tend to pick apart everything I read or watch for both what worked and what didn't seem to work as well. I'm still processing what I think about this build-up of the NK as a serious existential threat, and yet who was vanquished in one battle (regardless of how challenging and overwhelming it was). I'm starting to think that I bought into the seriousness of it such that this episode seemed to treat it a little too casually. But I'm open to re-assessing that, and also seeing what the remaining episodes have to say, as it were.

Completely and frivolously off-topic, but everytime I see the Children, I think this must be what Barkskin looks like on Druids (or Ironbark on those we cast it on) :-p
