I think the best example would be Bladerunner. As a standalone movie it is outstanding. As an adaptation of the also outstanding novel ‘Do Androids Dream of Electric Sheep’ it is an appalling travesty that totally misses the point.
Similarly, as a novel DADOES is outstanding in its brilliance, but if seen from the perspective of someone who has watched and loved the movie it is a travesty.
Better to think of them as two stories told in the same setting with some of the same characters - much like the vast range of quality in the many Sherlock Holmes interpretations out there.
