Those Who Read the Hearts of Evil

One of his best performance! Kim Nam-gil never disappoints his fans and even non-fans. This guy is really something. He truly deserve that Daesang award. He was outstanding in this drama. And the drama, as a fan of crime, psychological thriller dramas, this is a masterpiece. Perfect casting. Great cinematography. Great work from the writers and director. I watched this drama straight and completed it in a day. Mind-blowing. It deserves a standing ovation! My second favorite psycohological thriller drama after Beyond Evil. If you are fond of those kinds of scenes, this is definitely a must-watch.

A captivating and binge worthy detective drama series, this is the Korean version of the hit series Mindhunter. Everything about this is on point. Amazing acting, script, cinematography, soundtrack and overall production value. Pretty much as good as it gets.

I usually watch Kim Nam Gil with playful and funny character. Here in this movie all his funny and playfulness are completely gone. He becomes very serious , persistent, and meticulous person. This proves that he worked hard to animate this character.

This is very serious drama unlike other korean drama that usually combine romantic and comedy into the movie to make more enjoyable to more people. I believe some persons might get bored to watch this. It is very idealistic. No romantic, no fun, nothing but thrill and suspense.

I think it will be classic. I don't think this kind of drama will arise again in 5 - 10 years from now.

Many compared Through the Darkness to the US series Mindhunter. Though they share some elements, they are completely different shows. One focuses on the mind of serial killers. This one focuses on the psychology of profilers.

They could not have found a better actor to portray an empath. And they couldn't have written a better script to profile the empath archetype: quiet, introverted, loner with few social connections. It's downright eerie how well the empath type was depicted. This personality type takes every emotion they're exposed to onto themselves. If they're not careful, their burden will consume them.

By contrast, the serial killers' stories were deliberately made crass and vulgar to underscore the banality of evil.

If you're going into this with a 'Korean Mindhunter' mindset, you'll likely be disappointed, like so many other commenters. But if you like intense psychological exploration, this is the show for you.

A very well put together 12 part series covering some horrific crimes in South Korea. Set in 1990 up to 2007 and based on a book of experiences of a famous Korean Profiler. Over 12 episodes it charts their infancy as a behavioural unit and the lack of support , funding or understanding from their police colleagues as to their relevance to each investigation. Hard to watch at times when some of the crimes were being recounted by the killers. I can imagine the real profilers didn't have an easy job. Superb cast in this with some familiar faces and a few new ones. The 2 male profiler leads are outstanding !!! Their facial expressions and studious examination of each case just pulls you in and you are rooting for them to catch the killer. I really hope there is a second series. We'll done everyone. Superb series !!!
