I supposed it may be controversial to say that I really liked "Tommyknockers," to the point that I feel a little miffed when SK talks about it being rubbish.
I tend to like his books in waves. I feel sometimes like he'll write a couple that seem "meh" to me, then he'll write two or three that I like, and then he'll write one that knocks me out. This is where re-reading comes in handy, because a lot of times I'll realize it wasn't so much the book that was "meh," but my frame of mind when I read it.
I do remember a time (early or mid-'90s, I think) when I lost interest in much of what he was writing, and then "Bag of Bones" tore my face off, it was so good.
