Kafka's novel doesn't have much of a story. A movie that tries to tell this strange, deceptive and repetitive tale is bound to frustrate and annoy its audience. As this is a very famous piece of literature, three state-sponsored TV stations from Austra, Germany and France decided to give it another try, as part of the obligations from their - in the mid 1990s still officially relevant - educational mandate.
Haneke's film remains close to the source material, while still staying somewhat watchable, for most of the time. That's not a small achievement. This is a deliberate literary adaptation, a not too obtrusive narrator adds the sound of Kafka's writing, which is an essential feature. The color scheme that's mostly close to black and white, but not everywhere, is an interesting decision. The art direction is okay. The cast is of course top-notch. The storyline is what it is, not great, not annoying, and there is most certainly no deep hidden meaning to discover.
Kafka himself didn't have access to some divine wisdoms and truths. He described a worldview, a sentiment, created a melody that was very influential in the 1950s to 1970s. Haneke's film does the best it can to bring it to the small screen.
Kafka didn't know how to finish his novel. It's been said that he was considering to just kill K. Off. But that would have been a boring cheat, Kafka accepting his own defeat. Therefore his novel stayed "fragmentary" and was published as such two years after his death. This film ends EXACTLY like his script - not the printed book - ends. It's a surprising and funny moment.
Today, of course, the logical ending seems to be obvious: If everything is lies within lies, people pretending to be from the castle are most likely not from the castle. So when K. Finally gets a coach "to the castle" - he ends up in another village. Fixed it. Once you know the melody, it's easy to do a Kafka. 6/10.
