It feels a bit clichéed to me to say this at this point but I can´t put it any other way: I agree with everything you say.
I´d love to read the book myself, Stephen King always cites it as one of his all time favourites. Also the Weird includes a short by Shirley Jackson that was also very movingly tragic to read. They included many quotes from the novel in the show which I know mostly because they also used it in other film versions.
So far I know of The Haunting from 1999. Starring Lili Taylor, Catherine-Zeta Jones and Liam Neeson.
It´s very flashy and has lots of very dated looking CGI effects in it.
And then there is the Haunting from 1963, which came out only 4 years after the novel, is very subtle yet effective. That´s a must see classic.
BTW. There was one scene in one episode of the show where there was Russ Tamblyn as a therapist that probably made you go: “Oh, it´s that mad doctor from Twin Peaks!” however the reason he was there was probably rather that he was in the 1963 Haunting, he is the second guy from the left in that picture.
So I think you can watch this now if you haven´t already.
I think I also know why I missed almost all of them…
Yeah, right. as if I´m looking at the background when Carla Gugino is in the foreground!
