Sans merci

From brutal hand-to-hand combat to wielding his signature baseball bat and mastering blade fights, Bones crack, bodies fly, and blood stains the walls of many villains' hideaways. So Ji Sub delivers an electrifying performance that sets a new standard for action storytelling.

Mercy for None lands its blood-soaked action sequences and sufficiently surprising plotting to stay engaging.

-The series maintains the high-energy melee flair that the best South Korean thrillers have, with stellar fight choreography.

-The duration of the episodes was good, each of which is between 30-40 mins long, which I found super refreshing. It doesn't make you bored.

-In conclusion, this show is only for fans of action and bloody violence.

Yes the amount of actors is STUPID yo I mean it really, I just want to see what's face the Netflix Procurement or Accounting and Finance team made when the director said "Yes I want them all, any problem?"

Action sequences was great, some part with too much CGI blood but meh not that weird.

The lighting was great though I love the tone which actually reflects the mood quite well.

The dialogue also great, some of plot twists, not that surprising but it was well written. The wording was great and actors did it well got me tearing abit, can make my heart heavy.

Overall, I bloody love this series I which it could be longerrrr!!!!!

I really loved non nonsense show, the action genere is clean cut, without any distributed slope, its simple ruthless honest as it progress, its definitely a Korean John kick series. For a simple continuous watch, which keeps viewer interested in complete one go watch, cinematography choreography of action sense is flawless there is no doubt this is one of the best action series of 2025, a simple known revenge story which gets better with each episode. With satisfying ending, there is no way to ignore the master action piece like this, its good action for limited series. With good story and well based acting.

I binge-watched this series in one sitting and absolutely loved it from beginning to end. Each episode kept me on the edge of my seat-there was never a dull moment! The fight scenes were spectacular, and the cast was truly an all-star lineup. I really appreciated how the story unfolded and wrapped up; it perfectly matched the title.

While many have likened it to a Korean version of John Wick, I believe So Ji Sub truly delivered in his role-he completely nailed it and left us wanting more. As a long-time fan of So Ji Sub who had been eagerly waiting for his return to the screen, I can confidently say this series marks a fantastic comeback for him. I'm excited to see what he takes on next!

"Mercy to None" wears its John Wick influences on its sleeve, but quickly carves out its own brutal, stylish identity ( this is what called inspiration not copy like other movie ) At its core, the series follows ex-assassin Rayna Cross as she's dragged back into the underworld she thought she'd left behind-an arc that will feel familiar to fans of Wick's single-minded pursuit of vengeance. Yet where "Mercy to None" truly shines is in the precision and inventiveness of its fight choreography and the depth of its world building.

What Works

Next-Level Fight Sequences: From quiet, tension-soaked close-quarters combat to sprawling, neon-lit warehouse brawls, every punch, kick, and weapon-swap is impeccably staged. The camera moves with purpose, giving just enough coverage to appreciate the skill on display without confusing the eye.

Rich Story Building: Unlike the comparatively lean narrative of a feature film, this series takes advantage of its episodic format. Side characters-from a cunning fixer to a burned-out mentor-are given room to breathe, deepening the stakes and making Rayna's journey more resonant.

Atmospheric World: A rain-splashed cityscape of gleaming skyscrapers and shadowy back-alleys feels lived-in and dangerous. The show's score-an edgy electronic pulse-underscores every heartbeat of suspense.

Where It Stumbles

Familiar Foundations: The opening setup leans heavily on the "one last job" trope, and viewers looking for radical plot twists may find the first two episodes a bit predictable.

Pacing Hiccups: A mid-season episode devoted almost entirely to exposition slows momentum; a tighter edit there would have sustained the series' breakneck energy.

Verdict "Mercy to None" doesn't just echo John Wick-it builds on that blueprint with richer characters and fight scenes that outshine their cinematic counterpart. If you crave well-crafted action and a darker, more immersive dive into an assassin's world, this series earns its stripes-8 out of 10 for delivering a vengeance thriller that's both familiar and fiercely original.
