Here (considered very quickly) is every non-Dark Tower, non-Short Story book I read of his, up and including when I completely gave up on him after Insomnia:
The Shining
The Long Walk (as Richard Bachman)
The Dead Zone
Misery
Carrie
Thinner (RB)
Salem’s Lot
The Stand (IMO, The Stand reads like four intertwined books, somehow. Two of them are excellent, two of them kind of suck. However, while reading it, you will feel like you are living it. Not recommended for a first-time King reader, as it requires some measure of indulgence.)
The Running Man (RB)
Dolores Claiborne (Love the way it’s written as though it’s a transcript of Dolores’ interrogation recording, and everyone else is poorly miked.)
It
Cujo
Christine
Gerlad’s Game
Below here is where he starts to get mediocre for me.
The Eyes of the Dragon
The Dark Half
Rage (RB)
Firestarter
Roadwork (RB)
The Talisman (Actually not too bad once I got past page 20 on about the 7th try.)
Needful Things
The Tommyknockers
And, for the single worst novel I have ever read:
Insomnia
Stopped reading him at all after that. Stopped buying novels, too, IIRC. Thanks Stephen!
I enjoyed the first three Dark Tower Books well enough, although I thought the second was rather weak. Since they are very definitely meant to be an epic, you can’t really consider them separately. The Wizard and the Glass (Dark Tower IV) took so long to come out, however, and so much dreck was released in the meantime, that I gave up on the series.
Agree with the above posters who say his short stories are the way to go. Dolan’s Cadillac is excellent, and The Boogeyman still creeps me out.
