A series that is reminiscent of the more famous series, The Gifted. Both star Nanon and Chimon, but Ohm is a nice addition here. Both series are also set in a school and have the students on a mission to expose the dark secrets of the school.

As a youth drama, Blacklist's focus on the students as the main characters is necessary but it also stretches one's credulity. The teacher who forms the secret group, Blacklist, to expose the school's dark secrets seems highly irresponsible and inconsistent. Yes, he is ultimately not portrayed as a really great teacher, but the characterization is baffling. As a student in the school years ago, the teacher had a friend who came to harm. He suspects the principal. And yet, the principal decided to let him be a teacher there anyway (for unconvincing reasons revealed at one point). And the first generation of students who make up Blacklist end up being KILLED in the process of their investigations yet this teacher has it in him to form another generation of Blacklist and has no qualms about putting the students at risk.

Perhaps we can explain that the teacher is fixated on exposing the principal's deeds and he's not such a perfect person anyway, but for someone who is so passionate about the cause, the teacher is conspicuously absent in many of Blacklist's meetings, merely setting them a mission and letting them discuss (or fight) amongst themselves before settling on a plan.

There's also the conspicuous absence of parents--Traffic gets into a lot of trouble and his sister, Fah, has disappeared, but the parents are never seen--not even a phone call or something is shown. Yes, this is fiction, but even the fictional world of the series has at least one mother crying for justice after her son almost dies in the school.

The story starts off being rather suspenseful and engaging and even fun. Traffic enrolls in a school to investigate the disappearance of his sister, Fah, and realizes that her disappearance is linked to a criminal group of which certain students are members. However, the series goes overboard with plot twists (which may still be ok, but the twists aren't always very convincing, e.g. the revelation that Andrew is sent by the principal to infiltrate Blacklist opens up holes that the writers can't patch despite scrambling to do so). Then addition of a second villain after the first one (the principal) has been nabbed is bizarre though it is not altogether unexpected. It is also bewildering that even after the principal's criminal organisation has been busted, it is still possible to order drugs from some underlings, as suggested by how Traffic calls a number only to realize that it is a number to order drugs. What's more, the riddle used to identify people in the know hasn't changed when he makes the call . (And it's a common riddle you can answer if you had heard of the riddle before. So much for a secret code.)

Perhaps the series would have been better if the writers had gone easy on the plot twists and focused more on character development. The characters do draw the viewer into the story, but there is little development though showing more of how their experiences have changed them would have been interesting.
