1. Andrew is crazy.
He was really crazy, he killed his wife and dared not face it and put himself into the set context. Thinking that he was a great law enforcement officer who came to the lunatic asylum to investigate the truth, he made up a long list of characters and plots. It's the ultimate fantasy. With that said, the other characters are all good people who help such a delirious patient out of danger and live in peace. (This kind of plot is less dramatic, I don't like it)
2. Teddy is not crazy.
I think so. It is more convincing and makes the story more interesting and exploratory. Teddy was a soldier who fought in the war and became a law enforcement officer. After the official found out that he was secretly investigating the Shutter Island, they deliberately set up a bureau to punish him. Out of a sense of justice and self-redemption, he walked towards the designed "Urn of Death" step by step. He told his accomplices everything he knew, only to be betrayed. The accomplices colluded with the doctors. And Teddy, who was trying to redeem himself, had too many burdens. He couldn't let go of his wife who died in the fire. What made him more sinful was the war he participated in and the "murder" in the war. When he entered Ward C and saw George, he said to Teddy: Then you'll never leave this island. Teddy was carrying so much baggage that he was stymied every step of the way. Because of this, he will never be able to escape the island. The Shutter Island is both an island of reality and an island of spirit.
Both George and Rachel, who was hiding in the cave, knew the inside story, so they were persecuted. And the legendary Laeddis never appeared, this is not important, he is just a victim of a big conspiracy, a white mouse in the experiment. With Teddy also dangerously trapped in the role of being an insider, it seems logical that he would be persecuted in the same way as the first two insiders.
It's terrifying that a normal person can be turned into a lunatic, and it's a breeze. No matter when and where, machinations are more creepy than sharp weapons. Rachel knows this, she said to Teddy: Once you admit that you are crazy, everything you do is crazy, whether it's rational defense or denial, fear or delusion, you're considered crazy.
The male protagonist, who wandered between Teddy and Andrew, finally compromised. And all this is disguise? Because always believed in Teddy's shrewdness. At the end of the ward, Sheehan shook his head with the doctors (conspirators) while chatting with the male protagonist. The shot given at the end of the film is a chilling beacon, and it's not hard to imagine the fate Teddy most likely faces.
The movie did not give an answer, leaving a long list of suspense. It is possible to welcome the birth of "Shutter Island 2". How I wish this happened.
