Dark/mind blowing crime/thrillers dramas

For future purposes, if you ever wish to watch upcoming thriller or crime dramas I would recommend looking into these two networks: OCN (Korea) and WOWOW (Japan). They usually produce shows of either genre, and frequently have series' airing every month. 

Shokuzai (2012)
Karamazov no Kyodai (2013)
Evil Minds (2015)
Hokuto (2017)
Bad Guys: City of Evil (2017)*
Day & Night (2017)*
Burning Ice (2017)
Iari: Mienai no Kao (2018)
Saka no Tochu no le (2019)
Instinct (2019)
Sleepless Society: Insomnia (2019)*
Danger of Her (2020)
The Victims Game (2020)*
A Murderous Affair in Horizon Tower (2020)
Light on Series: The Long Night (2020)
After Dark (2020)

It's not listed on the database here, but I also recommend Giri/Haji (2019)* it's a joint Japanese and British production that falls into the category you are interested in. 

(all series that have an asterisk at the end of their release year are all available on Netflix)
