It was the summer of 2002. People were still reeling from the twist in The Sixth Sense and the comic book deconstruction of Unbreakable. Then came the crop circles. If you were there, you remember the marketing—it was eerie, quiet, and felt dangerously real. Signs M Night Shyamalan wasn’t just a movie about space invaders; it was a movie about a guy who lost his wife and his faith, who just happened to have a bunch of tall, grey nuisances running around his cornfield.
Most sci-fi movies go big. They show the White House exploding or Will Smith punching an alien in the face. Shyamalan went the other way. He locked us in a basement with a family eating their "last supper" while something scratched at the door. It’s been over twenty years, and we’re still arguing about the water. We're still debating whether they were even aliens at all. Honestly, that’s why it sticks.
The "Water Plot Hole" That Isn't Actually a Hole
Let’s address the elephant in the room. Or rather, the glass of water on the end table.
The internet loves to complain that the aliens in Signs M Night Shyamalan are "stupid" for invading a planet that is 70% water when water is basically acid to them. It sounds like a massive oversight. But if you actually look at the subtext, the movie isn't a documentary on interstellar logistics. It's a parable.
There is a very loud segment of the fanbase that argues these creatures weren't extraterrestrials from a distant galaxy, but rather demons. Think about it. Graham Hess, played by Mel Gibson, is a former priest who has "given up" on God. The "aliens" don't use technology. They don't have ships in the traditional sense—at least not ones we see doing anything high-tech. They use their hands. They are defeated by "holy" water—water left around by a girl who many viewers interpret as an angelic or prophetic figure.
Even if you don't buy the demon theory, the "water flaw" ignores human history. We send people into freezing tundras and scorching deserts all the time for resources. Maybe they were desperate. Maybe they were just scouting. Does it matter? Not really. The movie is about the "signs" in Graham's life, not the biology of the invaders.

Mastery of the "Off-Screen" Scare
Shyamalan is a polarizing guy, but in 2002, his grasp on tension was untouchable. He understood that what you don't see is way scarier than a CGI monster.
Take the birthday party scene in Brazil. It’s grainy, handheld footage. A group of kids is screaming, a car passes, and for a split second, a figure walks across an alleyway. It’s one of the most effective jump scares in cinema history because it feels like something you’d actually see on the news. It’s messy. It’s brief.
- The clicking sounds on the baby monitor.
- The dog barking at something invisible on the roof.
- The rustling of the corn stalks when the wind isn't blowing.
These are the things that keep you up at night. He used a minimalist score by James Newton Howard—just three recurring notes—to build a sense of dread that never really lets up. Most modern horror movies throw everything at the screen. Signs M Night Shyamalan makes you stare at a dark vent and do the work yourself.
Performance and the Weight of Grief
It’s easy to forget how good the acting is here because we’re so focused on the plot twists. Mel Gibson plays Graham with a hollowed-out intensity. He isn't a hero; he's a man who is actively angry at the universe. Joaquin Phoenix, as Merrill, provides the perfect foil. He’s a failed minor-league baseball player who still has a shred of wonder left in him.
The scene where they sit around the table for their final meal is heartbreaking. Graham refuses to pray. He screams at his kids to eat. It’s a domestic drama that just happens to be interrupted by a global invasion. This is the secret sauce of early Shyamalan. He anchors the supernatural in the mundane. If you don't care about the family, you don't care if the door holds.

Why the Ending Still Divides Us
The climax of Signs M Night Shyamalan relies on the idea that everything happens for a reason. Ray Reddy’s (played by Shyamalan himself) car accident, Bo’s habit of leaving water glasses everywhere, Merrill’s baseball record, Morgan’s asthma—it all converges.
To some, it’s a beautiful "clockwork universe" moment. To others, it feels like a coincidence stretched to the breaking point. But that’s the point of the movie’s central monologue. There are two types of people: those who see signs and those who see luck. The movie doesn't try to bridge the gap between them; it just asks you which one you are.
Real-World Legacy and Influence
You can see the DNA of Signs in movies like A Quiet Place or 10 Cloverfield Lane. It pioneered the "contained invasion" subgenre. We don't need to see the Pentagon's war room to know the world is ending. We just need to see the fear in a father's eyes.
Interestingly, the film was a massive financial success, grossing over $408 million worldwide. It proved that audiences were hungry for high-concept thrillers that didn't rely on massive explosions. It also marked the peak of "The Twist" era before it became a bit of a parody of itself in later films like The Happening.
How to Re-watch Signs in 2026
If you’re going back to watch it today, try to ignore the "logic" of the invasion for a second. Instead, watch it as a study of post-9/11 anxiety. It was filmed and released shortly after the attacks, and that feeling of "the world changed overnight and we aren't safe in our own homes" is baked into every frame.

Watch for these specific details:
- The way the camera lingers on the pantry door.
- The reflection in the TV screen when it's turned off.
- The specific wording Graham uses when he talks about his wife’s final moments.
The movie is more of a puzzle than a creature feature. Whether you think it’s a masterpiece or a flawed experiment, its impact on the cultural zeitgeist is undeniable. It taught a generation to be afraid of their own backyards and to maybe, just maybe, keep a few extra glasses of water around the house.
Practical Takeaways for Film Fans
If you're looking to dive deeper into the world of Signs M Night Shyamalan, start by comparing it to his later work like Knock at the Cabin. You'll see a recurring theme: people trapped in a single location forced to make a choice about their beliefs.
Check out the "making of" documentaries if you can find them. The way they built the actual crop circles—rather than using CGI—adds a layer of physical reality to the film that still holds up on 4K displays. Avoid looking for a "scientific" explanation for the aliens' behavior; the film operates on the logic of faith and folklore, not biology. Accept the movie's internal rules, and the tension becomes much more effective. Finally, pay attention to the sound design. If you have a decent surround sound setup, the scratching and clicking noises in the third act are designed to move around the room, mimicking the feeling of being hunted in a basement.
It’s not just a movie about aliens. It’s a movie about the scary, beautiful, and sometimes violent ways we find our way back to what we believe in.
