[Answer]

There were things I liked and disliked about ep 3.

Pros:

- Arya coming in to kill the NK was dope
- The way lyanna went out was dope (just wish they showed the giant doing more damage first, possibly killing a B-list character like Gendry or Podrick first)
- Beric being brought back to life all those times for the sole purpose of protecting Arya
- Theon getting some balls and going after NK shows character development

Cons:
- Bran is still a worthless piece of trash character. Literally feels useless in every sense and I had figured maybe he would have some significant purpose vs the night king.... he didn't
- Sending all the dothraki out by themselves to get slaughtered was retarded
- The first like 20 mins was all blurry as shit and hard to see much of anything going on. I get that it's supposed to be snowy/blizzarding, but fuck, it was bad quality television
- They really underutilized the conflicts coming from the dead rising in the crypt (everyone knew it was going to happen but they didn't really focus on it much)

Overall, I was kinda disappointed in the episode but the more I think about it the more content I can be with what it was. My biggest disappointment is how unfulfilling it seems that the NK is dead. Pretty much everything Sharp said. Like, I understand that they're trying to build to a bigger crux of fighting against Cersei and possible fighting against each other for the throne - but this was literally the single biggest build-up for most of the original seasons and now it just seems sort of like a side-quest.

But my assumption is that it's gonna be Dany vs Jon at the end of it, and each will have their own dragon. But Dany clearly doesn't have dothraki anymore. Idk, will be interesting to see what happens.

On the topic of military tactics, and assuming that everyone was oblivious to the fact that the NK would raise dead in the crypts - it would've made the most sense for them to have more fighters stationed in the crypt. When you're drastically outnumbered the way they were, the best thing you can do is retreat into a cave or something with only one point of entry, which will limit the number of nightwalkers that can get into the cave at any one given moment. Fighting them in an open field where they can surround you is fucking stupid.
