Mr. King's early work was terrific. He always had a problem with endings, though. The "big picture" wasn't always there, but the small things were terrific. His short stories were great too (The Body, Shawshank Redemption, both made into movies, Apt Pupil and The Breathing Method were not and should never be).
His later stuff has been less good. Also he's gotten political. He was always a liberal, and didn't try too hard to hide it, but it wasn't in your face. Now it seems that all liberals do is get in your face.
The Stand was good. The Shining was very good (the book not the movie).
Defimitely his best one, IMO.
His early stuff was fun. His later stuff was dull.
