You, too, can write a Stephen King novel! You will need:
1 quiet small town in Maine.
1 outsider, alien or disease
1 annoying child with both an affliction and a special ability
Several adults willing to be led by said child
Several peripheral characters, to be killed off at intervals
1 person, preferably female, to spout religiously tinged pseudo-profundities
1 giant, hideous underground monster
2 shy people who fall in love
1 writer, professor or other expert to explain what's happening to the other characters
Several hundred unnecessary pages
Mix, allow to set for five minutes, and sell to television!
(I'm only ripping on King because he can create such great yarns when he wants to. it just seems like he wants to less and less.)
