I have no idea why the reviews are so bad but, Through the darkness is one of the best psychological thrillers I have ever seen. The show is about criminal profiling first being introduced into South Korea to help discover 'what makes a serial killer?', 'what attributes does a person have that makes them commit a crime?' and to be able to link crimes thus making catching a killer a lot easier.

The drama centres around Hayoung and Youngsoo who decide to take up the difficult task of creating their own behavioural analysis unit to aid investigators catching serial killers. Of course in the beginning of the show there is plenty of ignorant characters who do not take them seriously but as the show progresses we see how helpful criminal profiling has become and the difference it has made to the justice system. Hayoung is a passionate character who will literally do anything in his power to show how reliable criminal profiling is and to prevent serial killings. The shows has different storylines with a new serial killer for each story set over a time period. Each story is completely different and shows the growth of criminal profiling as well as how detrimental to your health working in this field can be. Through the darkness is different to other kdramas in the same genre as it is realistic and based off of real events and research from a South Korean criminal profiler. Therefore it isn't overly dramatic or has any unrealistic plots.

The acting? Perfect!

If you enjoyed the American drama 'Criminal minds', then this drama is 100% for you. This is a realistic portrayal of serial killers so please keep that in mind.

(bare in mind some scenes can be upsetting and overwhelming)
