Didn't Benjen Stark say he couldn't follow Bran all the way to Castle Black because there is some kind of magic property to the wall that forces him, and the white walkers, to stay away?

But Night King and Ice Dragon can get right up close, no problem?

Also, what the fuck happened to the wall? Don't tell me it was "melted". Everything we know about the Walkers/Wights says that their body chemistry makes it impossible for any of these creatures to conjure up flames.

Honestly I was expecting the breach of the wall to be a lot more dramatic. I mean, if it was this easy....why didn't they do it before?

If you're gonna say, "dragon", ok then. But that means that they were actually truly trapped beyond the wall, and all anyone had to do to protect the realm was NOT give them a dragon. Sounds like they could have just sealed the tunnels, disbanded the Night's Watch, and never given it another thought.

I feel like the show has been very patiently exposing the threat from the dead. They were just a vague nightmare to most people through like 5 and a half seasons. By the end of season 6 though, we were led to believe that they were a massive, imminent, and potentially unstoppable threat. Now, just a season later we find out they were actually completely powerless but for Jon's brilliant idea to go wight-hunting?
