Nothing much to be said. It is a typical european movie, mostly French, of half a century ago. In short. the anti-thesis of anything Hollywood could deliver. This is probably one of the reasons for the low evaluation.
It scratches on the borderline to surrealism, and does so very much on purpose. Office and bank buildings, even court rooms and private houses could have been taken directly from Kafka.
I do agree, this is NOT hollywoodian, though fits totally to the plot. Which starts by the dismissal of a leading bank employee after some investment money was found to be embezzled one way or another. While going through harrowing (surrealist or maybe futuristic) employment interviews, the bank employee still tries to prove his innocense, and is much helped by his wife.
The music also fits to the almost surreal settings and leaves the end basically open.
If you go for cinematography, close to surreal, and development (and discovery) of characters, this movie could easily grasp you throughout its length.
