Finally. Korea has finally come out with a top notch police/procedural drama. It's also from a cable broadcaster,which says a lot. Cable in Korea is really stepping it up recently. The plot follows a special team of detectives that work together to solve cases that only have a "10%" chance of being cracked. The cases are dark and twisted and wonderfully portrayed. Each member of the team has an interesting backstory and is played to perfection. Joo Sang Wook was amazing as the "less than noble" team leader with the soulful eyes. My favorite character overall, was Kim Sang Ho's lazy bum-detective character who is actually quite clever. TEN has amazing cinematography and visual effects ... it seems a lot more artistic than the usual cop drama. The music is also lovely. BREATHE by Mad Soul Child is a hauntingly amazing song. Overall, a slick and exciting mystery series that features great acting. Can't wait for the movie that will conclude the cliffhanger at the end of episode 10. ;)
