movies, you might have a tough time as not many good movies have been adapted from Dean Koontz books.

However, there are about three of these Dean Koontz movies that are almost as good as Stephen King movies.
Generally regarded as one of the best book by Dean Koontz, "Watchers" qualifies as a Dean Koontz movie that is almost as good as a Stephen King movie, primarily for the unique characters throughout the story. These consist of a boy, a dog and a monster who are hunting people throughout the story. The first movie made in the early '80s was a good enough Dean Koontz movie that was almost as good as a Stephen King movie to spawn two sequels, which were really bad.
With a big Hollywood budget and a cast that consisted of talent like Ben Affleck and Liev Schreiber, "Phantoms" is one of the three Dean Koontz movies that are almost as good as Stephen King movies as it has the Hollywood pedigree to be something that people will watch and talk about for years to come. Unfortunately, the movie wasn't very good; the movie was a flop and this Dean Koontz movie that was almost as good as a Stephen King movie is not really remembered anymore, except in jokes.
This thriller and horror film based on the Dean Koontz novel is a Dean Koontz movie that is almost as good as a Stephen King movie, as it starred Jeff Goldblum and Alicia Silverstone, making it something that people at least initially wanted to see. However, the book didn't seem to translate well between page and screen and this Dean Koontz movie that was almost as good as a Stephen King movie has since been forgotten about.
