I got to know Stephen King as a latchkey kid watching reruns of movies like IT, The Shining, Green Mile and Shawshank Redemption and seeing this intersting-looking series of books they were pushing at the local bookstore. (Dark Tower anthology set, at the time the latest book was Wizard and Glass) so you could say I was one of those peon plebs, but I -was- 9.
It was only in my first job at a comic book store in my teens that they had the ongoings and eventual hardcovers of the Dark Tower prequels by Peter David and Jae Lee. They were always more expensive than the usual collected editions but there was something that made me interested in this high-falutin'-fantasy Western it seemed to be.
My first relationship was over as I went into the military but my Dad got me the first edition of Vol. 1: The Gunslinger and I was hungry for more. I bought the full 7 book saga but reached only the beginning of Book 4, because I felt that somewhere around the second book, Drawing of the Three, it was... Weird. Not Grant Morrison-surreal-longform-weird, but this was a stream-of-consciousness-no-plan-whatsoever-weird. I had to rationalize that it was King's version of writing a Fallout scenario.
I don't know the circumstances but I was spoiled the ending of the Dark Tower and felt really cheated, especially finding out that these books were basically unplanned with no definitive ending in mind when he began. I felt Stephen King is a lot like George Lucas and Hideo Kojima - he needs a check in place to bounce ideas off of, an Editor to tell him "no, you're crazy".
It's why when the Dark Tower movie came out, I was among the minority of liking the movie because it wasn't chock-full of 1001 ideas he wrote about, rather just stripping it down without the weird focus on sex, questionable characters like Loretta Dean (I think that was her name) and the subplot with the serial killer who made her a Schizo and killed Jake.
