How Shutter Island turns you delusional

Rating: 10/10 (20 March 2020)

Spoilers Ahead!
When I say this movie turns you delusional, I don't mean it literally turns you crazy. I mean that it makes you believe and trust the delusional and falsehood of "Andrews" mind. You follow this rollercoaster of a story through the eyes of the severely emotionally disturbed protagonist as he takes you through how his mind processes the things around him. The buildup of what inevitably arrives makes you question what is real. Is this all a game as from what George told him while going through only the most insane area of the mental institution? Is the protagonist still being tricked into believing he is an inmate himself as from his cave hallucination? Obviously he is emotionally disturbed and unstable from his past trauma, but the way the movie is laid out, it doesn't make it so far fetched that the twist might not be a twist. Perhaps we just watched the institution turn a U.S Marshall into believing the past he once thought of his own was a lie. Now i'm not saying that's true, there's no doubt in my mind this movie is about a immensely emotionally damaged man coping with the tragic lose of his family, but it is just a cool thought that I had.
