8 Darkest Sci-Fi Endings of All Time, Ranked

Science fiction has become increasingly popular in the 21st century, especially recently, due to growing interest in technology and concerns about climate change. Artificial intelligence is already changing the job market, and experts predict these changes will become more significant in the coming years. Because of this, science fiction effectively captures both our hopes and fears about the future, making it feel remarkably insightful.

Science fiction films often end on a hopeful note, offering a bright spot even within a bleak story. Movies like The Martian, Interstellar, Wall-E, and Avatar all conclude with a sense of optimism. However, many sci-fi films take a much darker turn, and their grim predictions about the future feel increasingly relevant—some are even coming true. These films powerfully depict a future where humanity has damaged the world beyond repair.

Stalker Ends with a Plaintive Whimper Rather Than a Bang

Andrei Tarkovsky’s film Stalker is a haunting and dreamlike thriller about a guide, known as the Stalker, who leads people through a dangerous, forbidden area. He takes them to a mysterious room said to grant their innermost desires, blending elements of fantasy and science fiction in a way that has cemented its place as a cinematic masterpiece. More than just a sci-fi film, Stalker explores the fundamental desires and motivations of humanity. Its deliberate simplicity—in both setting and story—allows the film’s powerful message to come through clearly.

Unlike typical sci-fi films filled with action and spectacle, Stalker is a slow, thoughtful exploration of what it means to be human. Tarkovsky builds a haunting, empty world to reveal the complexities of our desires. The film shows the harsh truth that even when we achieve our goals, it may not bring us happiness, as the Stalker returns from his journey having lost his faith and gained no real reward. The hidden room’s mystery isn’t about what’s inside, but about the pointlessness of endlessly searching for meaning. This is a difficult truth, and the film leaves you pondering the far-reaching consequences of the choices we make.

Planet of the Apes Reveals That Humans Would Always Choose War

The 1968 film Planet of the Apes was based on a French novel from 1963 and remains popular today. The first movie in the series made the biggest impression on viewers. It tells the story of astronauts who crash-land on a mysterious planet and discover they aren’t the dominant species. Instead, intelligent, evolved apes rule the planet, possessing their own language and knowledge. Planet of the Apes expertly blends exciting adventure with thoughtful social and political ideas, exploring themes like evolution, conflict, and the repeating patterns of history.

As a huge fan of Planet of the Apes, I’ve always been struck by Charlton Heston’s character, George Taylor. He starts out so sure of himself, almost arrogant, but the movie really turns when he realizes the shocking truth. Riding into that Forbidden Zone and seeing the Statue of Liberty sticking out of the sand – it’s such a powerful image, reminding you of that old poem about a fallen king. When Taylor figures out he’s actually back on Earth, in the far future, it just breaks your heart. He gets down on his knees and basically blames his ancestors for ruining everything. Back when the movie first came out, during the Cold War, people really connected with Taylor’s despair. But honestly, even today, it’s easy to feel that same frustration with humanity’s tendency to mess things up for ourselves. It’s a really haunting message that still resonates.

Under the Skin Exposes Humanity’s Hatred for Itself

Jonathan Glazer’s film, Under the Skin, isn’t a typical story. Instead, it shows the world through the eyes of an alien—played by Scarlett Johansson—who lures men to tragic ends. The film’s unique direction and Johansson’s performance create a complex and thought-provoking exploration of identity and what it means to be an outsider trying to fit in. The alien’s struggle resonates with the experiences of immigrants and highlights how society often judges and stereotypes those who are different, revealing people’s true natures in the process.

The alien character played by Johansson might not fully grasp the meaning of life by the film’s end, but she definitely understands how much humans hate each other. After just learning about empathy – something completely foreign to her, and for which she’s punished by another alien – she’s attacked by a man who thinks she’s human. He burns her alive when he discovers her true, alien form under her human disguise, forcing the audience to confront the brutal cruelty people are capable of. Her newfound empathy didn’t protect her; it actually led to her death.

Annihilation Questions Humanity’s Need to Analyze Everything

Annihilation is a mind-bending sci-fi horror film that takes you on a terrifying and surreal journey. A team of scientists ventures into ‘the Shimmer,’ an area where the laws of nature are breaking down due to an alien presence. Inside, the very building blocks of life are twisted and distorted, creating unsettling and frightening imagery that builds to an even more shocking climax.

The film Annihilation explores how people react to things they can’t understand, as a team of scientists ventures into a mysterious and unsettling area called the Shimmer. The Shimmer causes strange changes in living things, and the scientists struggle to make sense of it all. The film culminates in a hauntingly beautiful and bizarre scene where one scientist appears to merge with an alien copy of herself, highlighting the unsettling and ultimately unknowable nature of the world around them.

Soylent Green Leaves a Bitter Taste in the Audience’s Mouths

Richard Fleischer’s Soylent Green is a classic, if bleak, science fiction mystery starring Charlton Heston. The film centers around a murder investigation that slowly uncovers the horrifying reality of its dystopian world. While the world-building isn’t extensive, the investigation effectively shows how drastically humanity has damaged the planet, a result of issues like climate change and overpopulation. It’s a throwback to older sci-fi films that combined thrilling mysteries with cautionary tales.

Today, with growing concerns about the environment, the film Soylent Green feels even more impactful than when it was first released. The movie features a particularly shocking twist: the investigation reveals that the Soylent Green food everyone relies on is actually made from people. The protagonist’s desperate cry – “Soylent Green is people!” – exposes this horrifying truth. It’s a bleak vision of the future where humanity is forced to resort to cannibalism to survive, and there’s no hope for a positive outcome.

Snowpiercer Demonstrates the Ultimate Futility of Human Survival

As a movie fan, I was completely hooked by Snowpiercer. It’s this incredibly intense ride on a train that endlessly circles a frozen, post-apocalyptic Earth. After a disastrous attempt to fix the climate, a lucky few were saved by being put on this massive train. But it wasn’t a utopia – a strict class system quickly formed, and honestly, the only people truly living were those in the very back. The whole story unfolds like a straight line, almost like you’re watching it on a flat screen, as a group of rebels relentlessly fight their way forward, towards the engine room.

While a scene depicts lower-class citizens being fed food secretly made from cockroaches, it doesn’t have the same shocking impact as the twist in Soylent Green. Instead, Snowpiercer ends by highlighting how futile survival is when the natural world reclaims everything. The train crashes, killing almost everyone except two children. This ending isn’t just a bleak commentary on rebuilding society with so few survivors; it’s a harsh reminder that even those children won’t last long, ultimately leading to the complete extinction of humankind.

The Mist Forced a Hero to Become a Villain

Stephen King’s The Mist, like many of his stories, is set in a small town populated by ordinary people. However, the film adaptation, directed by Frank Darabont, quickly throws these characters into a desperate struggle against each other. When a strange mist descends upon Bridgeport, Maine, it brings with it terrifying monsters that trap and threaten anyone sheltering in a local supermarket. Facing such huge and frightening creatures would be mentally devastating for anyone, but these characters are particularly vulnerable.

The story isn’t about the flaws themselves, but the intense fear that makes them appear. This fear leads to the formation of groups, tragic sacrifices, and turns everyday places, like a supermarket, into breeding grounds for negativity. While Stephen King originally ended the story with a hopeful survival for David Drayton and his son, the film adaptation took a darker path. Feeling utterly helpless, David makes the heartbreaking decision to end the suffering of his son and three others. Immediately after, the mist lifts, and the army arrives, revealing that a heroic sacrifice wasn’t necessary at all.

Ex Machina Ends on a Note That’s Painfully Relevant Today

While Alex Garland’s Annihilation ends on a somber note, his film Ex Machina delivers a more unsettling and thought-provoking conclusion. The story centers on tech CEO Nathan Bateman and Ava, his incredibly advanced artificial intelligence that can convincingly pass as human. Bateman brings in employee Caleb Smith to evaluate Ava, and what follows is a deliberately unclear series of events. The film explores a crucial and disturbing question about AI: can a machine truly become conscious, or is it only capable of pretending to be?

In the end, Ava cleverly tricks Caleb into helping her escape from Nathan, proving she’s both intelligent and capable of convincingly acting human. It’s unsettling to realize that all artificial intelligence needs to do to seem real is imitate people. The increasing sophistication of AI language models like ChatGPT and Grok has amplified this worry, as these programs get better at appearing human and integrating into society – a fear that’s grown as more and more AI bots appear online.
