7 seasons of build up leading to a massive battle that even dwarfs LOTR's Battle of Helms Deep? The women, excluding Dany, turning out to be the real badasses of out of everyone? In particular Arya keeping it real, when the whole time most people thought that it was going to be a showdown between Jon Snow and the Night King.

The thing is though, I think the whole White Walker storyline was a misdirect. They were only a plot device to weaken the heroes to the point where Cersei could easily take them down. The major deaths are going to come when Cersei's army and Euron's fleet shows up to wipe out most of Winterfell.

They simply can't beat King's Landing so it might just come down to a sneak attack to assassinate Cersei.

I mean just keep in mind the shit is called Game of Thrones not Attack of the White Walkers.
