Vigilante

Both show deals wanting revenge for the greater peace of mind to whomever is involved........ notable performance by both the MLs in the shows

Both have antihero, police officer male leads who punish criminals who escape the law. They deal with themes such as morality, justice, and the fallible legal system. Keibuho Daimajin is Japanese, while Vigilante is Korean. Also similar to the 2010 Japanese dorama Joker Yurusarezaru Sousakan.

The story is similar to vigilante. The character development is really good and you will love the character throughout the drama. Don't read the comment and just was the show.

Just, if you liked one, I’m pretty sure you’ll like the other. They both have action, good plot (gripping), and very nice acting.

Both "Taxi Driver S2" and "Vigilante" feature protagonists who, disillusioned with the legal system, take justice into their own hands to punish criminals who have evaded the law.

Both explore justice and moral conscience through different lenses. While Vigilante dives into the psychology of vengeance and lawlessness, Officer Black Belt focuses on growth, redemption, and the realization that justice isn’t just about strength — it’s about responsibility and becoming the kind of person who can uphold it.

Kim Ji Yong begins living two entirely different lives. On weekdays, he's a model student at the police university. During the weekends, he punishes criminals who'd received light sentences and continue to commit criminal acts. Now called Vigilante, Ji Yong receives help from admirer Cho Kang Ok. Meanwhile, Detective Cho Heon chases after the man called Vigilante.

Both shows are about pressure for societal change, urged on through violence on the wings of journalism that is morally dubious to say the least. Both shows have themes of revenge and justice and are fast paced.

Both of them offer intense storylines that delve into the complexities of youth, crime, and retribution.

Both shows have Yoo Jitae in them, got the same vibe and very similiar main characters (vigilante lead, journalist helping him, antagonist trying to stop him etc.)

Justice Outside the Lines:
• Both shows deal with characters who challenge the boundaries of the law to pursue what they believe is real justice.
• They explore vigilantism within structured systems, highlighting the gap between law and morality.

Critique of Institutional Failures:
• Each drama examines flaws within Korean institutions—whether in law enforcement, education, or the military.
• They raise questions about how systems protect power and neglect the vulnerable.

Emotionally Driven Action:
• While action-heavy, both series use physical conflict to reflect deeper emotional or social struggles.

Realistic Tone:
• Both dramas have a grounded, raw aesthetic that matches their serious themes. They avoid glamorizing violence and instead portray its consequences and toll.

Social Commentary with Impact:
• Vigilante and D.P. each offer sharp critiques of Korean society, especially how authority is used or misused. The storytelling is direct and thought-provoking, encouraging reflection beyond entertainment.

The main characters in both dramas went through an ordeal that changed them, especially when the law fails them repeatedly. They decide to take matters into their hands to reveal the injustice in the world around them.

Both are violent, action-packed shows that do not hold back from bloody fight scenes and death. There is a theme of revenge in both but in A Shop for Killers it’s a bit more complicated. Both MLs kill people.

Protagonist with extensive access to info delivering justice to unheard victims through their own means

The genres are not exactly the same (Murderer Report is a psychological thriller while Vigilante is an action thriller - and heavy on the action) but I found they were both asking the same questions. Both are also very solid watches.
