Sadly, I don’t think there could’ve been much done to make The Shining much better (scope and scale) as long as AHS had to be a megahouse. The more I think about it the more hate I have for that show LOL.
I do LOVE Stranger Things, though, and even if It’d (see what I did there) be too thematically similar, I’d be cool with It. An ‘80s nostalgia themed HHN would be awesome—though again, AHS Cult would throw a wrench in that. As would another Purge—hopefully that would be contained to a second Blumhouse. If the new Halloween (interesting that it’s erasing everything post the original) is the main focus, a second Blumhouse could work.
Then again, given how the Storyteller and Cold Blind Terror were shoehorned into 15, I suppose “Stranger Things” have happened.
I suppose you could throw in Thing, maybe Poltergeist? To avoid being too similar to Forsaken, Fog could be a scare-zone (yeah Dead Man’s Wharf but still).
Vamp ‘88 would be obvious. Wonder what major conflict/eventof the ‘80s you could put the Nightingales in without it being insensitive (I saw someone suggest a Holocaust themed NG house once, LOL).
If a 3D house is needed, could make it an homage to classic arcade games—think the description for Anxiety in 2000.
