Carsten Höller, Decision: At his best he channels Willy Wonka, but the spectacle becomes boring

I recently watched Orson Welles’ The Trial for the first time, his 1962 film adaptation of the Kafka novel. The terror on the face of Anthony Perkins as Josef K as he runs through the long corridors of the modern bureaucratic nightmare was fresh in my mind as I trudged in total darkness through Decision Corridors (2015), an installation by Carsten Höller, comprised of a series of steel corridors. It is the first work in his new exhibition, Decision, at the Hayward Gallery, London.
