What the hell? That's it?
[spoiler]That's the end of the white walkers? After 7 seasons of build up and ominous foreboding about the end of the world, that's all we get?
That means you literally could have just not included them at all in the show and literally nothing would have changed.
I was counting on them to win the game of thrones and send the world into an icy wasteland and instead that entire time was wasted on an irrelevant, meaningless, useless plot device that ended up going nowhere?
What a complete waste of air time. I haven't been this disappointed since the Sopranos finale. [/spoiler]
