A great psychological drama

Rating: 9/10 (7 August 2019)

I've watched many movies of Scorsese. He loves picturing inner worlds of characters. Psychological context is a major element of his storytelling style.
Beyond Scorsese's general storytelling preferences, Shutter Island not only focuses on psycohological motivations of characters, but also it is a movie that directly deals with psychology.
It can be said that this movie's most magnificent feature underlies its ability to make viewer feel a profound emphaty with characters.
Who are insane? How can we distunguish if a person is insane or not? How can people assumed to be insane disprove their insanity; would we easily be convinced to them? Can you easily accept insanity diagnosis about you?
All these questions find very powerful answers in this movie.
