I was a huge Stephen King fan in my younger days, and have read everything on the list up to 1994, except The Cycle of the Werewolf. After 1994, Rose Madder, all the Dark Tower(s), Cell, Bag of Bones and the Outsider. (A few. Green Mile and Pet Semetary I've only seen the film).
I've read Night Shift, Different Seasons, Skeleton Crew, Nightmares, and Everything's Eventual.
The Talisman, The Stand, Tommyknockers and the Dark Tower are my faves. (apparently I have a thing for EPIC length books!) And some of his short stories are truly fantastic, I am the Doorway and Autopsy Room 4 stand out to me.
There are a few good audio books on youtube of his, which is where I found the Outsider. A decent story, but it fell right into his somewhat overused plot devices, so I saw what was coming from about a third of the way in, which is why i don't rush out to read his newer stuff anymore, sadly.
Another thing i find a bit weird about Stephen King is that two of his arguably most (commercially) successful stories turned films are NOT HORROR? Shawshank Redemption and the Green Mile, which are imho, the ones most of the general population know, but the plots are so different to anything else he has done.
