All i can say is that it has been good enough that I have watched all 13 episodes. Haven't read the book. King isn't my kind of author. But I like the premise of the story, which kept me coming back; however, this program has "milk it" written all over it. Anyone remember "Lost"?
It seems to me that producers have in their little minds that people are brainwave challenged. And yes, maybe more than half the country are challenged but that doesn't mean that a possible intelligent show (that it could have been) should suffer the consequences and be dumbed down itself.
Maybe it was the book? Can't speak to that but I do know that I think I'll just pass on Season 2 and beyond. I'm not going to be strung along for the dairy ride.
