The first two Godfather films, Fight Club and Battle Royale manage to balance the adaptive requirements with a touch of class. Those films more than make up for all the thousands of horrible films which manage to mangle the source material and - in the case of Battle Royale - manage to raise the profile of the original text in the process. It really doesn't matter that a film adaptation is a complete waste of time and money, because nothing that film producers do has any effect on the novels. The worst film, in regards to the Stephen King films noted above, must be regarded as Running Man, which swapped out a dark, dystopian thriller for a camp, clumsy, embarrassing mess of bad 80s FX and cheesy one-liners. If you go back and read the original, it's actually a horrifically prescient tale which foreshadows the financial crisis, reality television, 9/11 and a host of social maladies which plague us. The film? It's basically Arnholt running around in a gaudy jumpsuit being spectacularly stupid.
