No chances are that was it for the white walkers and they'll just move on to fighting cersi.
Yeah, I think the White Walkers are done for the series, and probably all the face-stealing stuff too. This whole season has been more straightforward, simply because they've only got 6 episodes and have to wrap everything up.
The White Walkers being wiped out felt abrupt, but on the other hand they did devote an entire, extended-length episode to just that one battle scene - one of only 6. No cuts back to King's Landing to see what Cersi is plotting, no big flashbacks, nothing but the battle.
The main thing that felt off to me was how few major characters died. About 5? And calling 3 of those major is a stretch.
Jorah - the foreshadowing in the prior episode was strong. His whole speech about how Tyrion is the right person to be her "hand" really sealed it. "I'm a good person now, so I can die."
Theon - he was just completely out of story.
The other 3 were pretty borderline; Ed? (whatshisname from the wall), The "Little Bear" and the guy who kept getting resurrected but lost the other guy who resurrected him (so you could kind of see that one coming).
Anyone else I forgot?
Every single peasant and farmer in the North seems to be dead now, that's gonna cause some issues...
