“Black Knight” takes a simple idea and builds a full dystopia around it. Set in 2071, the world is covered in air pollution, and the only way to survive is to breathe through oxygen tanks and masks. The delivery drivers who drop them off are the real power in society. Netflix released all six episodes on May 12, 2023.
The show follows a small group of these drivers, led by Kim Woo-bin as 5-8, Kang You-seok as Yoon Sa Wol, Esom as Jung Seol-a, and Song Seung-heon as Ryu Seok. They are not just couriers. They are the ones who decide who gets to live.

The World Behind the Masks
Cho Ui-seok directs the series, and he fills the screen with wide shots of a city buried under haze. The air pollution is not just a set piece. It shapes every scene, every decision, every character’s fate. The show treats the environment as a character itself, and that choice pays off.
The delivery drivers themselves are the other big draw. The source material lists a full cast of named drivers, including Kim Eui-sung as Tick-tock Grandpa, Nam Kyung-eup as Chairman Ryu Jae Jin, Jin Kyung as President of Korea Chae Jin Kyung, Roh Yoon-seo as Jung Seul-ah, Lee Ju-seung as Useless, Lee Sang-jin as Dumb-dumb, Lee E-dam as 4-1, and Lee Soon-won as 3-3. That list alone shows how much ground the show covers.
What Works
The show earns its premise by letting the drivers’ lives take center stage. Their relationships, their loyalties, and their daily jobs matter more than any one fight scene. The action holds up too. Cho stages chase sequences and fights with real energy, even in a world that mostly stays still.
The supporting cast also gives the show depth. Kang You-seok plays Yoon Sa Wol with a quiet strength that anchors the early episodes, while Song Seung-heon brings menace to Ryu Seok without ever tipping into cartoon villainy. Esom’s Jung Seol-a adds a layer of mystery that keeps the middle episodes moving.
Where It Falls Short
The show’s biggest weakness is pacing. Some middle episodes drag, and the plot slows down when it should be building toward a final push. The webtoon on which it is based is by Lee Yun-kyun, and the show occasionally feels like it is following that source too closely rather than finding its own shape.
There are also moments where the world-building overshadows the human drama. A few episodes spend too much time explaining systems and rules rather than showing the drivers living them. That balance is hard to strike, and the show does not always get it right.
Ranking the Episodes
If you want to watch the best of what “Black Knight” offers, here is how the episodes stack up:
- The first episode sets the tone with a strong hook.
- The second episode deepens the stakes around the delivery system.
- The fourth episode delivers some of the show’s best action.
- The fifth episode drags slightly but introduces new threats.
- The sixth episode wraps things up with a decent finale.
Final Word
“Black Knight” is a solid entry in the dystopian genre. It does not reinvent the wheel, but it does not need to. The setting is fresh, the cast is strong, and the central idea is compelling enough to carry six episodes.
The show stumbles in the middle, but it recovers in time for a satisfying finish. For viewers who enjoy slow-burn sci-fi with real human stakes, this is worth a look. For those who want constant spectacle, the middle stretch might test patience.
