This the same Stephen King as the one who re-issued The Stand with all the pages editors had removed put back in, thereby showing the world the absolute necessity of editors?
I think I agree that in many cases King's endings let down the book (Tommyknockers is an example) but sometimes he hits one out of the park (Firestarter worked very well for me, as did Christine).
But the real king of "Ruin a Good Idea with The Explanation" is Dean Koontz. I had to stop reading his books. I loved he set-ups but hated his trite reasons why things were happening like they were.
Never read any Twilight books, largely because in a post "Vampire LeStat" world I feel Vampires Are Stupid. There isn't anything anyone can say about them that is new and interesting no matter what you say they eat or when they can or cannot go abroad amongst people. I *did* read a short in which vampires kept herion-addicted humans for the high, but the rest of the story simply wasn't worth the idea.
And for me the sooner the current craze for Zombies is over the better. The Dead rise. Yawn. Even the White Walkers are tedious. We know this because GRRM stopped writing about them yonks ago, having baited and switched the reader at about halfway through book one of A Game Of Pagecounts.
I'll watch GoT on TV next year just for the spectacle, but to the idea that the dead are taking over Westeros I say "about time", and I'm done with the books since book 5: A Blithering with Behemoths.
