S Line

The concept is excellent, and the show had great potential. It could have been a powerful series if more depth and effort had been put into its development. However, the execution felt lacking - almost as if the series had been cut short or rushed. Many events were incomplete, and several characters and plot points were left unexplained. This made the ending and some key moments lose their impact.

It had the potential to be truly outstanding, but it needed stronger writing and a more cohesive storyline.

I don't watch a lot of Kdrama, because majority are just cliché formulas but the S line was genuinely interesting. However, that being said it was rushed.

From episode 1-3 it was perfect, genuinely interesting and shook us to the core but from 4-5, it was too slow space but also felt very rushed at the same time and 6....let's not even begin with it.

The mystery is genuinely good, and I recommend everyone to watch it fro 1-5 and just watch a YouTube summary for episode 6, because at that point it's just Bolognese. Would've worked better as an ending if the executed it well enough.

Doesn't necessarily deserve the hate it gets because it does discuss about a bit of complication issues, but that being said, if it focus on it more and took its time, it would have worked numbers.

S Line is a dark and gripping mini-series that combines mystery, psychological tension, and social commentary in a unique and disturbing way.

The story follows a girl who can see red lines above people's heads, revealing their sexual relationships. For others, the line is visible only if they wear some random glasses.

Each episode follows a different case where someone gets the glasses and their life takes a dramatic turn. What starts as curiosity often ends in tragedy, and the deeper the story went, the more disturbing it became.

The pacing was slow but reasonable. With only 6 episodes, the story was building effectively, however out of nowhere, the final episode takes a whole different path and the series ends up disastrously without giving a proper explanation of glasses, the girl's ability to see the red lines or the supposedly cult that was seen in the final episode. The show could have been so good, but the finale made it into a disappointing affair eventually.

Overall, S Line is a wasted potential, that had a great story, but went wrong due to it's confusing and unexplainable ending.

My Rating : 5/10.

At the heart of S Line is a darkly imaginative premise: What if sexual connections between people became visible as red threads floating above their heads?

The thing is it had the potential to be such a good drama. I watched 1-4 ep in one go as it got me hooked up but the ending really destroyed it. Like seriously I can't even express how disappointing the 5-6 ep is. The ending was foolish tbh.

-WASTE OF TIME-

"S Line" is the first mini series, or perhaps even a micro series, from director and screenwriter Ahn Joo young, marking her second project in the film industry.

Format

Unlike traditional Korean dramas, which typically span 24 one hour episodes, or even standard mini series with around 12 installments, "S Line" consists of just 6 episodes. This makes it an ideal choice for one or two evenings of viewing. The concise runtime ensures there are no unnecessary scenes or filler dialogue, resulting in a dynamic and richly layered narrative.

Style: "Korean Anime"?

The series shows clear influence from anime, particularly in its unexpected and almost absurdly imaginative ending. However, it avoids the exaggerated acting often associated with Japanese productions, maintaining a more natural and restrained tone. The characters are emotionally expressive yet believable, and the fantastical elements are grounded in a way that feels almost plausible.

Acting and Characters

For many viewers, including myself, the cast will be a pleasant surprise. While I wasn't familiar with all the actors beforehand, each performance feels fully realized and compelling. The characters are well developed, charismatic, and distinct. Credit goes to both the writing and the cast's convincing portrayals. If there's one drawback, it's that some supporting roles deserved more screen time to deepen their arcs.

Plot and Pacing

"S Line" masterfully builds tension from start to finish. The pacing is brisk but never rushed, with each scene meaningfully advancing the plot. The story delivers unexpected twists, emotionally charged moments, and a subtle anime inspired aesthetic that keeps the viewer engaged throughout. Like many Korean dramas, it plays skillfully with the audience's emotions, and succeeds.

The Main Drawback: The Ending

The finale, unfortunately, feels inconsistent with the rest of the series. Had it delivered a more cohesive resolution, "S Line" could have achieved significantly higher critical acclaim. The last episode introduces a tone that feels detached and slightly unresolved, which may leave some viewers disappointed. That said, the first five episodes remain strong and thoroughly enjoyable.

Is It Worth Watching?

Yes, especially if you appreciate unconventional storytelling and are willing to overlook a flawed ending. "S Line" offers a refreshing format, strong performances, and a unique blend of realism and fantasy. Its short length makes it a low commitment watch with plenty of payoff. Recommended for fans of innovative mini series and character driven narratives.
