"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.

I think I've finally found my new all-time favorite thriller. The action is non-stop, and there are so many crazy twists that it keeps you on the edge of your seat the whole time.
Mercy for None is definitely an action-packed thrill ride. If you like bloody, brutal fights, you'll love this show. It's not for the faint of heart, for sure, but I couldn't take my eyes off of my screen for a second. It's one of those shows where the plot unfolds gradually, but there are enough hints and clues to keep you guessing. The pacing is so perfect. There are plenty of tense moments, and lots of quick cuts, but the show never feels too hectic.
The fight choreography is absolutely incredible. I never thought anything could top the martial arts in John Wick, but I was seriously impressed with the fight scenes in Mercy for None. Every single one of the fights felt believable and realistic, and the stunts and visual effects were perfect. I also like that they put a ton of creativity into the fights, and the action sequences are designed to blend into the narrative really well, so they don't feel completely out of place.
Plus, it's fun to watch So Ji-Sub kicking butt and looking so dapper while doing it. He's been in some other action flicks, so I already knew he could act, but I wasn't expecting his performance in this one to be on another level. He delivers the lines convincingly and never misses a beat, and the fight scenes are so detailed.
I thought Mercy for None was a bit of an odd choice to cast So Ji-Sub. He plays a former gangster, which isn't exactly a typical character for him, and yet he does it perfectly.

I really enjoyed this show. I appreciate how succinct it told the story, nothing was dragged out. It has phenomenal fighting and interesting/new (to me) camera work. The only reason why I don't give it a 10 is because I liked other shows a tad bit more. Specifically: "Bloodhounds" and "Worst of Evil".
Both shows also have amazing fighting, but Bloodhounds and Worst of Evil have more fleshed-out stories (even if Bloodhounds retcon'd near the end due to a scandal involving one of its actors). Mercy For None's storytelling cuts out just a little bit too much, enough so that I was wishing I cared more about the main character.
Nevertheless, it's an exciting show. Totally still worth the time. Highly recommend.

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.
Episode 1 Impressions
I'm going to start this off by saying if you've liked any violent Korean revenge thrillers in the past two decades than Mercy for None will probably be your cup of tea.
The fight choreography is crisp and bloody with punchy SFX for each punch. Every hit connects with intensity and the camera moves around enough to keep fight scenes entertaining instead of disorienting.
The plot is not too bad either. It seems to be your typical run of the mill Korean revenge setup. Something happens that motivates an over powered character to want to exact revenge. It doesn't really bother me that much because I came for the action. The story is good enough to hold your attention, albeit a little confusing for the first 30 minutes.
The production design, cinematography are all top notch and I was surprised by the production values. Varied locations and slick cinematography help to make sure you eyes are never really board.
Mercy for None is great so far after one episode. The premiere did a good job hooking me and now I want to see what is going to happen next. If you're here for the action I don't think you will leave disappointed. As long as you can suspend your disbelief from time to time, but that is part of the fun!
