I haven't read the books, so I'm really not up on a lot of things as many of you guys are, but Im confused about the predictions of Bran dying.
Isn't that what the Night King wants so he can erase all human memory? So why would that happen?
Because the way you hike up the drama and make a positive ending feel earned is by making the audience feel as though the good guys have already lost before the big turnaround.
Of course, if there's a major defeat (as I anticipate) this weekend, most people will assume that at least some of the good guys will figure it out before the close of episode 6. But if Bran is killed and the Night King seemingly achieves his "goal" then the reaction will be "WELL WHAT THE
? DO THEY DO NOW?!"
This is basically what Marvel did with Avengers: Infinity War.
(and you can see this basically formula at work in most good action movies)
