The problem, of course, is how they (D&D) got to that point in the first place - where Bran gets randomly touched by an undead minion of a white walker while.....idk, playing with Jojen outside? And then killing Jojen, a fucking living greenseer, for that mistake that surely D&D wrote, and that touch being enough for the White Walkers to know where Bran is and get through the magical wards set by the Three Eyed Raven. And then the aftermath of that journey is that 3ER dies, Jojen dies, Meera is forgotten, and their father, literally the only living witness to L+R=J in the books, is just completely not introduced. And Bran becomes a powerful warg and...philosopher? after literally nothing. You can see that GRRM gave them the Hodor piece, but not how shit led up to it, or the fallout from it.
Man, I get angry thinking of seasons 5 and onward of that show.
