By about the 4 installment it was getting just a little too weird for my imagination to picture the scenery and world. Up until then, he was doing a great job of building character(s), backstory, and weaving a really odd world that had "moved on". You can tell he wanted (and even had) an "epic odyssey" and that King tends to write in a sort of "stream of consciousness" style (that you also tend to read it in). I mean, the man just cranks out text at some ungodly speed and you have to sort of just let it "wash over you and let it take you with the current".... but after a while, you begin to wonder where in the hell it's headed and if you really want to drift with it any more. I ended up swimming to shore and walking away from it. Probably not my best metaphor.
