Some of his books just aren't very good. I loved the concept of Under the Dome, but the villains were so cartoonish I just couldn't take them seriously and I skipped whole chapters to get back to the protagonists.

Cell was a great concept, an alien signal spread via cell towers turns people into zombies, but it literally has no ending. It's like King went "Oh, shit, deadline is today? Eh, fuck it, ship it. Good enough!"

But man, when he's on point with stuff like It, the Stand, Insomnia, the Dark Tower? Hard to touch.
