Bad Guys (2014)

In both shows the son/daughter of the main lead are killed.
The main leads both go above and beyond to catch the criminal

Both revolve around crime and justice, and neither focuses on romance. Both dramas contain a character(s) with a mysterious backstory. The big and obvious difference is the supernatural element brought on by "Vampire Prosecutor."

Found families, stereotypical anti-heroes as heroes, action, and lovable characters with appropriate back stories!

Another OCN crime thriller drama. Some gritty suspense and action-packed sequences. Not only does this show deliver on the slick and edgy directing style we’ve come to expect from this genre, but Bad Guys also boasts a strong narrative and tough characters.

Action packed!!! Amazing actors. Never sitting down without being on the edge of your seat!!
The chemistry between all the actors was tremendous.
Plot was well thought out!

Both are about a team of criminals working together for a bigger goal.
Bad guys is a bit darker so the focus is a bit more on the psychological & crime elements.

Gritty. Amazing action. Solid acting. Bromance heavy. Main lead Taemin becomes the killer's target and Park Hae Jin gets similarly affected in a different way.

Both dramas are about a group of people who chase down bad people. Bad Guys is with criminals employed by the police, and Taxi Driver is with employees of a taxi company who are employed to take revenge on bad people. Both groups don't exactly use legal methods, and aren't afraid to be pretty violent against the bad people.

There is an episode of Bad Guys dealing with serial murders in the rain that reminded me of the movie Memories of Murder where the female victims where all killed when it rains.

They both are pretty cruel dramas. Both are made by the same channel, OCN. Both have these special teams solving the cruelest crimes. I really recommend both ones

They have same premise guys can’t remember accuses of a crime. And a cop desperate to solve case will do anything.

Both dramas has:
-smart characters as the main ones.
-killers.
-detectives who are involved in the case.
-characters with a deep story life.

It's not really similar in terms of plot, but it gives me the same vibes

The only similarity is corruption...

If you loved Park Hae Jin 's psychopathic character in this, definitely watch Voice season 2 and 3 for its spectacular performance by Lee Jin Wook. Voice 2 and 3 did an amazing job at fleshing out character like this that progressively worsen because of evil, manipulative forces around them. Enjoy!

This is the original Korean series it's based on. Bad guys, criminals, given the chance to regain their freedom if they help catch other criminals.
