As a very long time Stephen King fan/reader/collector I was wary of this show when first announced, but had to watch it at least once.
I must say after the first episode on USA this past Sunday (if you missed it don't worry, it is on like a dozen times) I was very pleased. The story so far sticks very close to the book (with modern day updating) and is extremely well done. Eventually it will go past the story in the novel, but without him sacrificing himself. When it ended I was very eager to see more and am happy to find out 13 episodes throughout the horrible TV summer months are planned.
Anthony Michael "Brat Pack" Hall was very good and doesn't even look like himself after the coma.
Check it out if you haven't - can't lose on a Summer Sunday night!
