Dreamcatcher was a terrible book, and even worse movie (Even ignoring for a moment that it's basically a rip-off of the theme from the Alien series, with the exception that the aliens are deliberately trying to take over). Hell, The Langoliers was better sci-fi than Dreamcatcher, as was The Tommyknockers.I thought that Dreamcatcher was some darn good sci-fi
I will agree though that King is more than just a horror writer. Dolores Claiborne, The Green Mile, Shawshank Redemption...just off the top of my head. It's just that most of his books are horror in nature, and most of his really good stories are, too. It, Pet Sematary, Carrie, The Shining, just to name a few.
