My latest column for Killings, where I look at film adaptations of novels, was published a couple of days ago:
The value of a novel adaptation is primarily how well it works as a film, and to a lesser extent, how well it expresses the essence of the source material rather than how well it mimics it. The book is never better than the film; the two are incomparable. It’s not reasonable to critique a film for not functioning in the same way that a novel does. A film may fail on cinematic grounds, but it should not be accused of failing on literary grounds.
