LIKE:
1.Jung Kyung Ho is alway my bias
2.cinematography
3.good actors and the kid is really cute

DISLIKE:
1. the ending.Sorry but I am not happy about the ending maybe because I hate the idea he committed suicide.

IT'S BETTER IF:
1.more character development especially Tae joo(Jung Kyung Ho)
2.the story is good because of the mystery of Tae Joo childhood but not really great because of the some uninterested minor case they solved.
3.good storyline about the main killer
