What is the story of Shutter Island, how can I not understand it, and what does it mean?

Analysis of the ending of "Shutter Island":

1. If "George Noyce has delusions, and Dr. Rachel is really a person", it means that George has never left Shutter Island, and Ted has never left. And Dr. Rachel's statement is true, Shutter Island does engage in inhumane human experimentation.

If "George Noyce has a delusion and Dr. Rachel does not exist", it means that neither George nor Ted have ever left Shutter Island, and the conversation between Ted and Dr. Rachel is purely his personal fantasy, and Shutter Island is just a normal mental hospital, but most of the patients are high-risk patients.

Video reviews. The atmosphere of "Shutter Island" begins from the first note that appears with the Paramount logo in the opening credits. Scorsese peels away reality like a craftsman.

Ted's war trauma in the decade after World War II is expressed in flashbacks. The typical symptoms of "post-war traumatic shock syndrome" can be seen in the men in the film, who wear ordinary suits and ties, smoke cigarettes in their hands, lower the brim of their hats and walk into the heavy rain, and pretend to be calm. All the details foreshadow a disturbing and terrible secret, and Ted's self-confidence and ego are constantly being eroded, all of which are impeccable under the director's arrangement.

The first possibility is that Teddy is Andrew Laeddis, a mentally ill person, and his fate may be two: first, ** successful, Andrew is awake, the doctor's purpose has been achieved, and there is no need for surgery; 2. ** failed, and Andrew was caught for surgery because of violence (in the lighthouse, the bald director said that Andrew was the most violent patient in the Shutter Island).

The second possibility is that Teddy is a law enforcement officer, so there are two ends for him: first, Teddy was driven crazy by the doctor on Shutter Island and became a real madman, and the crisis of Shutter Island was automatically resolved; 2. Teddy remains awake and the doctors at Shutter Island surgically dispose of Teddy.
