I actually completely agree with @Khrz about King's endings... A lot of the time he loses the pacing at the very end and then just blows everything up. He did it in his first book Carrie, he did it in The Shining, he did it in Needful Things, he did it in IT... and these are some of my favorite books of his.

If anything, one thing the movie version of The Shining improved massively was the ending. Super classy and iconic ending.
