The action is quite something by the female boxing champ. Convincing. The faults are glaring - a lack of continuity in the story telling. Also the jumping around in time breaks up the tension - should have been chronological. Why the sister got into so much trouble is a bit too much. Harder to stomach than the over the top fight sequences.

Not quite worth watching.

This has 'I see the devil' vibe to it. though there are some plot holes, i truly enjoy it. revenge is sweet.

If in Taken, they took his daughter, and in John Wick, they killed his dog, it was definitely a bad idea to mess with her sister.

I agree that it has some holes in the story line, but that doesn't make it a bad movie. The actors and actresses delivered a wonderful performance and the plot is MIND. BLOWING. Like, I wasn't sure if the movie was good or bad for me because it was messing with my brain and my emotions.

Either way, they're definitely impacting the audience, so good job!

Lead Lee Si-young is incredible in this movie. She really gets to show off her boxing skills, and it's absolutely action packed, but there are so, so many holes within the screenwriting and overall story arc. It's almost like you're thrown into one scene, a one day action film that gives you zero background about the young girl Eun-hye and her sister. I appreciated the film for its use of great action shots and intensity in the fighting scenes, but it doesn't do much more within an hour and a half. The crazy thing is, the writer-directors chose such an important topic that it absolutely could have had more of an arc but ended up letting the viewer down by not living up to it.

There's always room in the action genre for more "one-man army" thrillers, but this has typically been a male-dominated space. It's therefore always great to see women getting in on the action. Lee Si-young (In Ae) is also no stranger to heavy-hitting, having a rather successful background in amateur boxing. This probably makes her fight choreography all that more believable.

No Mercy falters only in two instances, the first being the convoluted story-telling and secondly, by subjecting the younger sister to one too many ordeals in such a short space of time, hence losing its emotional weight somewhat. But those gripes aside, the action scenes are well coordinated and the revenge aspect is quite satisfying. It's the type of movie that caters to our natural instinct of (justifiably) punching numerous henchmen in the face.

No Mercy is one of the better action thrillers I have seen of late, with a strong female-led cast.
