According to the tally by the online content service ranking site FlixPatrol on the 12th, the Netflix series

'A Killer Paradox' scored 354 points on the 11th, securing the 4th place among Netflix TV series.

It ranked 1st in 11 countries worldwide, including South Korea, Bangladesh, Hungary, India, Malaysia, Pakistan, the Philippines, Singapore, Thailand, and Vietnam. 'A Killer Paradox' is based on the webtoon of the same name by writer Kkomabi and tells the story of an ordinary man who accidentally starts committing murders and the detective who relentlessly pursues him. The series is directed by Lee Chang-hee, known for 'Strangers from Hell' and 'The Vanished Night.'

The series is praised for completing a unique K-thriller with its original world, characters, and the charm of comic imagination, filling the gaps with a meticulous and unique perspective. Choi Woo Sik plays the role of Lee Tang, a college student who awakens the ability to discern evil after an accidental murder; Son Suk Goo plays the role of Detective Jangnam, equipped with exceptional intuition and instinct; and Lee Hee-jun plays the role of the mysterious pursuer Songchon, chasing Lee Tang and Jangnam, delivering a strong acting synergy.

'A Killer Paradox' poses a heavy question, "Is this right?" through the dilemma of a character who discerns and kills 'criminals deserving of death' and the one chasing after him, providing food for thought. 

However, those expecting the satisfaction of a dark hero might be disappointed, and opinions may differ on the approach to crime and murder.
