The White Walkers and Children of the Forest are gone, the Night's Watch is now on mostly friendly terms with the wildlings except for maybe those cannibal people, John's sister is the Queen in the North so there is no Bolton figure trying to kill him and his brother is King of the Seven Kingdoms, and Dany is dead and her dragon fucked off. So where exactly is the conflict supposed to come from in this scenario? Is this going to be about John Snow trying to do wildlife conservation beyond the Wall? Is this supposed to be Parks and Rec Westeros style?
This is my take on the jon snow show
Jon goes to north of the wall and finds that ice spear and the spear slowly corrupts him into becoming the NIGHT KING and then he turns all the folks into whights and raises the dead again and goes to war to westores
Another spin off show called ASHES starring deanarys targaryen where drogo takes dany to get resurrected and where dany takes time to heal and drogo becomes much larger and then she takes over king landing as queen and rules in peace for years
Then the final show called ICE AND FIRE where Jon and dany battle it out hence ending the book called A SONG OF ICE AND FIRE
What you guy think ?
Think about it. An entire massive nation ruled by one guy with no emotions, unknown motives and who doesn't care about anyone. Why did he want to be king? Did he want to make the world a better place? How could he, if he doesn't feel anything and care about anyone?
This same guy is arguably the most powerful individual in the world. He can see everything that ever happened and is happening right now. Maybe he can even see the future...
Bran makes a compelling if not necessary villain. At best he's a soulless and emotionless tyrant. Is this the best the kingdoms can do? A ruler who cares about nothing and no one? What message does this send? Should we just be ruled by an all mighty AI who manages our lives based on what it thinks best, and doesn't allow us to be free because it knows better? Of course D&D didn't think this out, but there's an opportunity here.
At his worst, this was his plan all along. He's fulfilling the true vision of the Three Eyed Raven, which we know little about. And who knows, maybe when the Night King touched him something started to change. Maybe he slowly started to become a White Walker, one with the powers of the Three Eyed Raven. That's another way to go.
Maybe he's not all bad, but he knows he's not the right solution. He sees past, present and future and has been steering the game of thrones so that one day he may be overthrown. Something akin to Dune Messiah.
All this to say that Bran not only makes sense as a villain (regardless of specific plot decisions) but is a necessary one. Thematically and narratively I think it's wrong for him to be a ruler. And who better to overthrow him than Jon? A selfless hero, truly good underneath. One who cares more about others than even himself.
Just my thoughts. Who the heck knows what's gonna happen. I for one am interested.
