A good who-done-it drama. The cat and mouse chase between the criminal profiler and his stalker was intriguing. The only drawback is that the show was too clever for its own good that sometimes you have to try and keep up. The romance between the socially-awkward professor and his assistant was endearing. The Professor's bestfriend is also a lovable character, but others not so much. Bad acting from the non-Chinese actors and the end seemed rushed with loose ends untied, and spent on unnecessary pairings.
