I mean the three eyed raven is the one protecting the living from an endless night? What??? I don't buy it. Wasn't the last raven in his cave for like a thousand years? Not interacting with any humans, only children of the forest? I don't get how this is the protector of humanity when he doesn't interact with humans at all, and his overall humanity is questionable. They gotta do better than that, or at least grrm gotta explain it better in the last books.
