An aspect of the Shutter Island is to record some attempt at self-knowledge and its failure in the horror of discovering that evil is incalculable and is not to be found outside.

Scorsese achieves consistency, symmetry and a rhythm of great power, robust construction and presentation of the theme the way it happens in movies that we recognize as ‘classic’.

From the first moment, when reality emerges through chaos, to the last, the self destruction in the cancellation of freedom, the film moves in a steady and high intensity. Over other possible readings, what impressed me most was the depiction of a paranoid existence as real, even as a choice of an omnipotent will, and the idea of a morality that excludes forgiveness completely. The idea is simple and old, which makes the success of Scorsese even greater.
