The problem with the miraculous saves isn't necessarily about the saves, but instead about the death teasing. They mentioned Jon going below the water. He should have been dead without a doubt. The writers fail to show how Jon escaped the wights, got back to the surface, and got out. Then, even after he got out, he still was facing the army of the undead. Again, here was a situation where there was no hope of escape. Then out of the blue, Jon's uncle comes riding up on a horse to sacrifice himself to save Jon. There is no way of him knowing Jon was there or in trouble. The only explanation would be that he saw the dragons flying and followed them out of curiosity. But even then it was way too convenient of a save. And even after Jon gets away on the horse, he should have died from hypothermia. He was out on the frozen lake for a least 12 hours, he was submerged into freezing waters, rode a horse with the freezing air blowing against him...He should have died but was absolutely fine. They even show his clothing being broken off him because it was frozen solid but he didn't show any damage from that event.
Another case of death teasing was Jamie riding towards Dany and her dragon. He was saved last minute by Bron but was thrown into a very deep lake in full armor. Surely he would have drown being that deep in the water and being pulled down by the weight of his armor. But the opening scene of the next episode is Bron and Jamie (still in full armor) about a mile from the point that they fell in, on the bank perfectly fine. That is so incredibly unbelievable....basically impossible.
It just feels like the writers want to continue the feel of GoT by putting the characters in mortal danger and making you think they are dead or going to die, but ruin it by impossibly saving them at the last second.
