No Mercy. No Justice. No point.

Highlights:
- One of the lead characters, Min Seo-Young, is quite likeable with her ambition and sense of justice
- There is a decently written revenge plot that is executed (albeit a horribly morbid and unsatisfying one)

Criticisms:
- WOW, there is a such thing as showing too much [autopsy scenes]
- All throughout the film, we are taken on an unsavory journey, where there is no "right" and the conclusion is THE LAST thing you'd want to see happen
- As far as the mystery goes, the plot is pretty decent, but the overused visual clichés [like slow motion for dramatic effect] make it seem really corny in tone
- THE MOVIE IS BORING; it took me several attempts to finish this one

Final thoughts - I love investigative thrillers/mystery more than most people, especially the plethora of outstanding South Korean titles in this amazing mixed genre. No Mercy is just too frustrating to recommend.

I don't believe every movie needs a happy ending to be entertaining, but there should be something for the viewer to feel good about after spending two hours of their time.

Watch Broken or The Deal instead and save your time on this one.

5.5/10
