Old Boy (2003)

similar revenge story that contains thrill and a psychopathic criminal.

both are about revenge and has the same kind of plot/story.

Oldboy and No Mercy has many similarities. To list a few major ones are Story is similar, Revenge is also similar. And finally at the climax a huge twist appears which makes the movie to the top level.

Both are revenge stories directed by Park Chan Wook. They both make the viewer feel sympathy for the protagonists. They are artistically made and they include complex characters.

I started it on midday and ended it at night. People who want to have action and a amazing story which is not really connected to the world where live will be disappointed.

However I loved how realistic it was. From beginning to end I was excited, shocked and realised that just little things can change a whole matter, your whole life, your character and surrounding.

This drama has a really good ending.
The acting was amazing.
The music fits really good.
... and I will rewatch it to unterstand it better.
Money can drive people crazy.

I recommend this both drama because , Male lead and Female lead
try to solve problem
In one drama explosion and another student murder/suicide

The main character is a tragic and melancholic old man who has lost everything and whose only way of living is with violence.

Old boy is the second installment of The Vengeance Trilogy, preceded by Sympathy for Mr. Vengeance and followed by Sympathy for Lady Vengeance.

benang merahnya sama-sama ingin balas dendam, namun storyline oldboy lebih dinamis kalau menurutku. gelombang emosinya lebih terasa, apalagi kalau sudah sampai di penghujung film yang dibuat plottwist. tapi untuk tingkat gore-nya masih juara i saw the devil sie

Both have the same theme which is revenge .
Oldboy is a movie and it has action sequences however Black revenge is more of a drama and mainly revenge is achieved through publishing scandals.
Just if someone is interested in revenge genre , both are pretty decent to watch once.

Both involve a killer who carry some meaning for the main character.

Prince Yeon San becomes engulfed with insanity as he kills those responsible for his mother's death. He appoints his longtime friend Im Sung Jae and his father to the position of retainer. They are then ordered to round up beautiful women from all parts of the country to pleasure Prince Yeon San. Women are taken regardless of their marriage status or social class, which causes widespread anger. Dan Hee is a beautiful woman, but she is a butcher from the lowest class. She saves Im Sung Jae from danger and then begs him to take her to the palace. Im Sung Jae refuses for his own personal reasons. Nevertheless, Dan Hee soon enters the palace. Im Sung Jae becomes conflicted and the Prince lusts after the beautiful Dan Hee.

Both "Oldboy" (2003) and "The Man from Nowhere" (2010) are South Korean films that delve into themes of ‘revenge and redemption’. In "Oldboy," a man seeks vengeance after being imprisoned for 15 years without explanation, while "The Man from Nowhere" follows a former special agent who embarks on a violent quest to rescue a kidnapped child. Both films are known for their intense action sequences, complex characters, and emotional depth, highlighting the lengths to which individuals will go for justice and personal redemption.

Disturbing plot and shocking scenes with many unexpected twists and turns of events.
Brutal, Bloody, Abnormal and apparently both 18+ rated for reasons.

With Characters that are not necessarily likable and protagonists where it's questionable if they are mentally healthy and display normal human behavior.

Not as dark/psychological as oldboy but, if you've seen oldboy you'll definitely get 'oldboy vibes' from this film. They're both thrillers. I won't say anymore because I feel it would ruin the experience, definitely a film you should go into without knowing anything.
