Absolutely agree with the thread, although there are some scenes in King's work that I do wonder about, such as the scene in IT (anyone who has read it will know what I mean, I'd rather not say what it was).
But King's work is so much deeper than horror. Look at the Green Mile. John Coffey's life could be considered a parallel with Jesus. Take his initials for a start, the fact that he is covered with scars that he doesn't remember getting, his constant tears for the evil of mankind and how he accepted that he is to die for crimes that were not of his doing.
The Shawshank Redeption...is there a better modern day example of a film in which hope is the underlying theme? Even the film adaptation captured this perfectly...when Andy took his shirt off and stood in the rain...so powerful!
The Body (Stand by Me) was another fantastic story of the loss of innocence and how all four boys were only twelve but each had their own demons to face and how they emerge from their two day hike far more mature than when they started.
As for The Shining, if ever there was an incredible moulding of Poe's Masque of the Red Death, The Shining is it. If you've read the Shining but not Poe's work do so. Reading the Shining after reading The Masque... really illustrates just how much King was influenced by Poe's creation.
I've been a bit disappointed with his more recent work (from Dreamcatcher onwards) and The Mist was pretty awful. Having said that I watched Rose Red and didn't enjoy it at first, but now I love it. It draws me right in
