If you’ve spent any time scrolling through Korean cinema circles lately, you’ve probably seen the name pop up. Shark: The Beginning isn't just another prison flick. It’s a gritty, visceral adaptation of the hit Kakao webtoon Shark by Woon and Kim Woo-sub. Most people expected a standard underdog story. They were wrong. This movie actually hits different because it balances the extreme violence of a survival drama with a surprisingly tender psychological core. It's about Cha Woo-sol, a victim of school violence who ends up in a juvenile detention center after a momentary lapse in restraint.
Kim Min-seok plays Woo-sol. You might remember him from Descendants of the Sun, but here? He's unrecognizable. He's scrawny. Terrified. Honestly, the way he portrays the physical manifestation of trauma—the flinching, the darting eyes—is what anchors the whole film. When he meets the former MMA champion Jeong Do-hyeon (played by Wi Ha-joon), the movie shifts from a "woe is me" tragedy into a tactical masterclass on survival.

What Shark The Beginning Gets Right About Combat
Let's talk about the fighting. Most action movies use "movie magic" where a guy learns to punch and suddenly he's Mike Tyson. Shark: The Beginning doesn't do that. It’s painful to watch at first. Do-hyeon doesn't teach Woo-sol how to be a hero; he teaches him how to be a shark—an animal that has to keep moving to breathe.
The choreography focuses on leverage. Since Woo-sol is smaller and weaker than the predators in the detention center, like the terrifying Bae Seok-chan, he can't win a fair fight. He has to use the environment. He has to use psychological warfare. The film highlights the "Southpaw" advantage and the importance of footwork over raw power. It's realistic. It’s messy. You feel every thud against the concrete floor.
The Psychological Weight of the Juvenile System
It’s easy to dismiss this as a "tough guy" movie. But if you look closer, it’s a scathing critique of how the system fails victims. Woo-sol isn't a criminal by nature. He’s a kid who was pushed until he snapped. The movie explores the paradox of a victim becoming a perpetrator just to stop being a victim.
- The Predator/Prey Dynamic: The detention center is a microcosm of the world outside.
- The Role of a Mentor: Jeong Do-hyeon isn't a "sensei." He's a man burdened by his own guilt, using Woo-sol as a way to find a shred of redemption.
- Physical Transformation: It’s not just about muscles. It’s about the "look" in the eyes changing from a deer in headlights to something much colder.
Most viewers don't realize how much the film deviates from the webtoon to make it feel more grounded. The webtoon is stylized and colorful; the movie is muted, gray, and claustrophobic. It makes the moments of triumph feel earned rather than scripted.
Why Wi Ha-joon Was the Perfect Casting Choice
Before he was the cop in Squid Game, Wi Ha-joon was proving he could carry a scene just by sitting still. His portrayal of Do-hyeon is stoic. He doesn't give long, soaring speeches about bravery. He gives blunt, often cruel advice. This "tough love" is actually what Woo-sol needs because the world he’s in doesn't have room for gentleness.
The chemistry between Kim Min-seok and Wi Ha-joon is the engine of the film. It's a platonic, rugged bond. It’s about two broken people trying to figure out how to stand upright in a world that wants them on their knees.
The Controversy of the Ending
Some fans of the original webtoon were a bit split on how the film handled the climax. In the source material, things are a bit more "shonen" (power-up style). The movie keeps it more tactical. Some felt it was too short. Others thought it was a perfect setup for the sequel, Shark: The Storm. Honestly, the pacing in the final twenty minutes is breathless. You're basically holding your breath as Woo-sol faces his literal and metaphorical demons.
The villain, Bae Seok-chan, played by Jung Won-chang, is genuinely unsettling. He’s not a cartoon villain. He’s the personification of every bully who never grew up, just got more dangerous. His obsession with Woo-sol isn't just about the initial fight; it's about the fact that Woo-sol refused to stay broken. That’s what actually pisses him off.
Deep Dive into the Production
Director Chae Yeo-jun clearly had a vision for the lighting. Notice how the colors shift. In the beginning, everything is overexposed or sickly yellow. As Woo-sol gains confidence and starts training under Do-hyeon, the palette becomes cooler, sharper. It’s a subtle visual cue for his mental sharpening.
They filmed in actual cramped locations to simulate the feeling of being trapped. The actors reportedly went through rigorous MMA training for months. You can see it in the way Kim Min-seok carries his shoulders by the end of the film. He isn't just "acting" tough; his body mechanics have changed.

Is it Worth the Watch?
Basically, yeah. If you like Cobra Kai but wish it was R-rated and set in a Korean prison, this is your movie. It’s also for anyone who has ever felt like they were at the bottom of the food chain. It’s a cathartic experience.
But don't go in expecting a happy-go-lucky underdog story. It’s grim. It’s a story about the cost of fighting back. Sometimes, to survive, you have to lose a part of yourself that was "nice."
How to Appreciate the Nuances
To really "get" Shark: The Beginning, pay attention to the silence. The movie uses very little music during the actual training sequences. You hear the breathing. You hear the sweat hitting the floor. It strips away the glamor of martial arts and shows it for what it is: repetitive, grueling labor.
- Look at the scars.
- Watch the hands.
- Pay attention to the background characters—they tell a story of their own about the hierarchy of the facility.
Actionable Next Steps for Fans
If you've already watched the film and want more, don't just stop there. The world of Shark is pretty expansive.
- Read the Webtoon: It’s available on various platforms and provides much more internal monologue for Woo-sol. You’ll understand his fear much better.
- Watch Shark: The Storm: The sequel continues the journey and dives deeper into the consequences of the first film's ending.
- Analyze the Techniques: If you’re into MMA, watch the training scenes again. They use real Southpaw strategies that are actually effective in real-life combat sports.
- Compare to Other K-Dramas: Watch Bloodhounds on Netflix if you enjoyed the grit and the brotherhood aspects. It covers similar ground but with a different stylistic flair.
The movie ends on a note that feels like a beginning—which, granted, is in the title. But it leaves you with a lingering question: Once you become a shark to survive, can you ever go back to being a human? That’s the real tragedy of Woo-sol’s journey. He won his freedom, but he had to become a predator to do it.
To fully grasp the impact, track the transformation of the lead character's posture from the first ten minutes to the final frame. The shift in his center of gravity tells more of the story than the dialogue ever could. This is visual storytelling at its most raw.
