I haven’t seen the boys. I tend not to enjoy the edgy deconstruction genres. I think they’re over shoot their pessimism. But I would ask, do characters really have a sense of danger associated with them? Game of Thrones was a series that supposedly did this, but I think that was very much a lie. Ned’s death and the red wedding were unexpected events. But they were largely setup for the story. After that many characters wore their shiniest plot armor. There was 0 chance Arya was going to die having left to some random murder cult and never actually impacting the story. Similarly for bran, and Jon, and most characters. Even most of the lesser characters had a fair chunk of plot armor. It’s largely unavoidable as plot threads spread out. I’d guess it’s fairly similar for the boys.
