16 Years Ago Today, This Criminally Underrated Thriller Gave Us 1 of the Most Debated Movie Endings Ever

by

Great thrillers keep you guessing right up to the very end, and one often-overlooked movie still sparks debate about its ending, even after 16 years. While thrillers are designed to be suspenseful, they usually resolve all mysteries before the film is over. That’s why it’s so remarkable when a movie delivers a surprising twist that seems to explain everything, yet still leaves audiences puzzled at the very last moment.

I still think about Shutter Island all the time, and it really bothers me that it doesn’t get talked about enough. It came out in 2010 with Leonardo DiCaprio, and honestly, it’s brilliant. What really sticks with me, even after all these years, is that ending. It’s so open to interpretation, and people are still debating what actually happened. That ambiguity is what makes the film so unforgettable, and honestly, the whole movie is just fantastic – it’s surprising it isn’t considered a classic.

Shutter Island Came Out 16 Years Ago & Is Still an Underrated Gem

Released on February 19, 2010, the film Shutter Island is a faithful adaptation of Dennis Lehane’s novel, though it does make some alterations. The story is set in the 1950s and centers around Leonardo DiCaprio’s character, who appears to be U.S. Marshal Edward “Teddy” Daniels. Teddy and his partner, played by Mark Ruffalo, are supposedly investigating a patient’s disappearance at a mental institution on a secluded island. As the film progresses, Teddy insists there’s a larger conspiracy at Ashecliffe Hospital, with staff conducting experiments on patients. The film’s ultimate twist reveals an even more disturbing truth.

The ending of Shutter Island reveals that Teddy isn’t who he seems; he’s actually Andrew, a patient in a mental hospital experiencing intense delusions. The film explains that his wife murdered their children, and he, in turn, killed her—an event that led to his hospitalization. Mark Ruffalo’s character is revealed to be Andrew’s doctor, and Ben Kingsley plays another psychiatrist who are both letting Andrew play out a fabricated scenario, hoping it will help him remember the truth. This method has worked before, but if they can’t prevent him from reverting to denial, they’ll have no choice but to perform a lobotomy, as he becomes dangerous when he loses touch with reality.

It’s true, Shutter Island is a complex and gripping thriller. What makes it so memorable isn’t just its surprising plot twists, but also Martin Scorsese’s brilliant way of revealing the story. The film is visually unsettling and features powerfully moving performances. Many consider it one of Scorsese’s most underrated works, and it truly establishes its brilliance in the final scene – a deliberately ambiguous conversation that continues to spark debate among viewers.

Shutter Island Has One of the Most Debated Movie Endings Ever

The movie Shutter Island ends with Teddy and Dr. Sheehan sharing a cigarette, and Teddy seems to have returned to his delusional state. He acts as if they’re working together and repeats his claims about a conspiracy at Ashecliffe, seemingly trying to convince the doctors he needs a lobotomy. As he walks towards what appears to be his fate, without a fight, he turns to Dr. Sheehan and asks a haunting question: “Would it be worse to live life as a monster, or to die believing you’re a good man?”

This naturally leads us to wonder if DiCaprio’s character is genuinely slipping back into his imagined reality. The dialogue suggests he could also be pretending, choosing a lobotomy instead. Considering his guilt about his wife’s death and his fear of causing further harm, this is a real possibility. It would explain his peaceful departure with Dr. Cawley and the staff, allowing him to face his fate with his memories intact and on his own terms. Otherwise, he might eventually end up undergoing the procedure anyway, but only after hurting others.

For years, people have discussed this on platforms like Reddit, and a common belief is that the last scene is open to interpretation. One Reddit user noted that Dr. Sheehan calls out “Teddy?” but doesn’t get a response, suggesting Leonardo DiCaprio’s character isn’t actually acting like ‘Teddy’ at that moment. The movie is deliberately unclear, allowing the audience to draw their own conclusions. Even after sixteen years, the ending remains debatable.
