I do see where you're coming from, but I don't think it's completely unnatural for the characters to be mentioning the crypts in this context. Whenever the crypts are mentioned they're at least brought up organically. Gendry mentions the crypts to Arya because he hasn't seen what she's capable of, Gilly and Davos mention the crypts to a little girl, Jon brings them up after Bran reveals himself to be the Night King's target. They're all perfectly reasonable points to bring up the fact that the crypts probably are the safest place to be. There's literally nowhere else for people to go if they're not soldiers. They can't send thousands of children and old people out into the North's countryside during the height of winter with an army of undead zombies on the loose, and they can't have them sat in the courtyard waiting for death. The crypts literally are the safest place to be, even if they're not necessarily a safe place to be. It's similar to what we're told to do when a house is on fire: the floor isn't necessarily a safe place to be, but it is the safest position under the circumstances.
And I'm not sure heavy foreshadowing will automatically diminish the impact of any dead Starks rising from their graves, should that happen. Think back to season 6. We're literally shown the destruction of the Sept of Baelor in 'Blood of My Blood' during Bran's visions after they escape the Three-Eyed-Raven's cave, four episodes before it actually happens. In 'No One', two episodes later, Cersei asks Qyburn about a "rumour" and he confirms that there is "more, much more". Hell, Johnathan Pryce (who played the High Sparrow) really let the cat out of the bag in an interview where he confirmed that "things don't end well" for his character. Piece all of that information together and you could have worked out before 'The Winds of Winter' that Cersei was going to blow the sept up to fuck. Knowing all of that beforehand still didn't stop that sequence being one of the best the show has ever produced. It's about the delivery, not about what comes beforehand. If a little Rickon Stark rises from his grave and chases Arya through the halls of Winterfell that's going to be frightening and emotional for a number of reasons, despite how much we've pieced together from this week's episode.
I understand what you are saying and do agree the crypts are mentioned organically; it is just the quantity and obviousness of the mentions that are problematic for me. As I said before, even if it is a red herring, I personally feel it was oversold and, in that overselling, some of the enjoyment is taken away. I want to work a bit for my theories for what is going to happen next and I just do not feel they are giving viewers that opportunity. I also think the slide into this sort of “payoff setup” scheme has been happening for some time in the show, it’s just become too prevalent in these last two episodes for me.
And our difference of opinion is just down to “excessive” foreshadowing having different impacts on our enjoyment of a story.
For you, it seems satisfaction is mostly down to the quality of realisation (with what came before it being important but not pivotal to your experience), which in of itself is very difficult to get right. I know a few that feel the same, including my missus, and they actually don’t like some of the movies I love because they feel the final resolution of story elements were poor, even if they were “expertly” setup.
Whilst for me the quality of the setup and foundational elements before it are key. That means excessive foreshadowing (my definition again being ‘spelling things out so the audience doesn’t have to do too much work putting things together’) impacts my enjoyment more than it does yours, as I value not being able to fully work out all potential outcomes beforehand (e.g., the ever rarer experience of being surprised). That experience so important to me that I am willing to forgive shortcomings in the resolution.
Nothing wrong with that difference. If anything, I do sometimes wish I could look past that sort of relatively obvious story development as a lot of other shows and books would be much more enjoyable for me because the final realisation of “bludgeoned” story elements are actually very high quality and would otherwise be very satisfying.
By the way, I agree they didn’t have much choice but to put the meek in the crypt, but I just don’t feel that has a bearing on how the writers/show runners portray the action and potential consequence in the story (en masse, in this case, in my opinion in an attempt to try to manufacture a bigger reaction to the outcome later).
In many ways, David Benioff and DB Weiss backed themselves in to the excessive foreshadowing corner with the decisions made about pacing and splitting the final arch in to two seasons the way it was, so perhaps it was unavoidable.
FWIW, the impact from the destruction of the great sept was diminished a bit for me by the setup. I even got the hair dryer from the missus for saying it was about to happen, which has seen me keep my thoughts about future potential plot developments to myself moving forward. ;-)
