Voz 2 (2018)

This is the next chapter to the the 1 season. The main detective can hear things that no one else can so more cases to solve.

well, so many people have given out recommendations and i am surprised that no one is yet to recommend Voice season 2 and 3 when the male lead character there is so similar to the one in Flower of Evil. in fact Voice series are OCN dramas so they are meant to be a lot darker and with less emphasis on romance which could be a plus for a genre like this. there is a good reason why the Voice series keep getting season's extension, you gotta watch it to know. enjoy!

Both shows pit the ML against a cult:
>> In SM2 the ML is trying to save/help his townsmen from a religious group who are really aiming to take away their money.
>> In Voice 2, both the ML and the FL discover and try to take down a cult/group of serial killers.

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!

-episodic cases
-a core story
-revenge based plots
-morally grey main leads
-no romance// but a lot of tension teamwork and chemistry
-good team
-badass leads
-really dark storylines
-blood gore and action
-taxi driver explores giving justice outside of the legal framework, whereas voice is very much pro-police (except out guy kangwoo love him sm)
-voice has a more personal and dark storyline than each of the characters in taxi driver, idk I feel more connected to voice characters
-both are thrilling, voice is more focused on uncovering a mystery whereas taxi driver focuses on bringing justice to the wronged, it's less mysterious
-amazing action thrillers both of them, keep you on the edge of your seats!
