Although the storyline is interesting, in my opinion the book was full of unnecessary descriptions and backgrounds of characters who won't appear again. I didn't think the main antagonist RF was particularly inspired, while the trash can guy (sorry english isn't my main language) is much more appealing, as we discover his instability and decreasing mental health. I somehow think King didn't know how to end the book, as the "fellowship of the ring" - style quest, just adds nothing at all. all in all I liked the book.
