I was watching a Korean show (through the dark) about detectives hunting serial killers, and one detective was trying to get a group together to do profiling and interview known serial killers, and he was trying to enlist another detective who he thought would be really good at that. I thought, this is like the Korean version of Mindhunter. It's kind of the same. 

Next thing, the first detective gives the other one a copy of the book, Mindhunter, saying that's what he is trying to do, except in Korea. 

What I really like about it is that it's not just a copy of Mindhunter. It's uniquely Korean and it's set in the 90's and based on true stories about how the Korean police started adopting similar methods to those used in the US, except about 20 years later. 

The time difference is interesting. The phenomenon of serial killers emerged in America in the 70's and then in Korea in the 90's.
