The Ghost Detective and Who Are You are both similar because they are about ghosts and detectives that deals with supernatural cases..

Both stories are about a guy from a rich family getting amnesia and disappearing from home. Both male leads are "adopted" by a poor female lead whom he meets by chance. Both male leads have their personalities changed due to memory loss and become sweeter and more down-to-earth people. The story is very similar.

Both are about ordinary people trying to live their life in the work place. You might even call them dramas about (among other things) office politics; it's just that Life took place in a hospital and Incomplete Life in a trading company.

Both movies are kinda similar.............

Both are Japanese jidaigeki movies that star Comedic Nomura Mansai in main role...........................................

Magic Martial Arts schools in both. Loner types start out with few friends but start showing their talents, getting some respect.

It might sound strange to compare a drama set in modern times with a historical drama, but honestly, if the setting doesn't bother you, then you might find these two dramas eerily similar.

-Both have ML's set on revenge against the FL's father.

-In both dramas, the MLs is first seen as light-hearted and charming, yet as the drama progresses, both ML become more serious and gloomier. Because of their darker disposition, both MLs push their love interests away.

-Both FL's are immature in the beginning (however, in Prosecutor Princess, it is more apparent). but they mature as the plot progresses.

-Park Shi Hoo is the ML for both dramas

There are plenty more similarities, but if I mentioned them, they would spoil the story too much.

Dark, Action, Fast paced, violent. Both movies are more focused on male characters and relationships. Personally I found Vile City lacking in some ways but overall good enough to enjoy

Interesting dancing shows, both have jisung, but the one focused only on teenager and is an audition show.
