My viewpoint on King's writing is that he's best off when he gets away from things that go bump in the night. Frankly, when King starts to describe the supernatural itself, he's dull. Now where he excels is getting into the mind of mad characters. He'll take a crazy person, put you in the middle of their monologue, and you come away feeling like you understand the madness, and have been sullied by the contact.
As for Under the Dome
, I enjoyed reading it, haven't seen the TV show. I liked the premise of the real villains being cruel alien kids
although I felt the resolution was a bit Deus ex Machina
in nature. I could see people breaking down as they did. They say that power corrupts, absolute power corrupts absolutely, and just a taste of power creates a man who would be a tyrant if he could be.
