My wife read it, but I never got around to it. I seem to remember her saying she liked it, but not as much as Kings older stuff. Trailer looks pretty good, I'm sure we'll see it too. When I find a good poster for the movie, I'll add it to the new horror board.
You're right, the newer King books I've read aren't as good as his earlier stuff, but this story had a nice twist at the end. I'm hoping the movie at least captures some of the terrifying vibe of the original Shining as this could really be considered a sequal.
