I would have given the first half more than 10 stars, if possible. Wow, was it ever good! So well-written, with smart dialogue, excellent acting, mystery and tension throughout. The music was very successful in addition to the tension.
Their voices were good and not screech-y (why do most C-dramas insist upon dubbing?). This was my first time of seeing Wallace Huo in anything, and I was impressed. his character, Simon Bo, was a criminal profiler and seemed able to pull the answers to clues out of thin air (suspend disbelief here). The developing relationship between the male and female leads was a pleasure to watch, and so amusing, since he had no people skills whatsoever. I didn't feel that them sleeping together that first date made any sense, since she could barely even kiss him on the cheek. However, her describing to him how he kisses? That was hot! The writers would have been better served to extend that "will they/won't they" tension, because the couple got boring after that. I loved that they were working on new crimes every couple of episodes, which kept it fresh. I also really enjoyed Andrew Yin as Simon's assistant/secretary. He and Simon had a wonderful bromance relationship going on and a lot of his lines were very amusing. I had to downgrade my rating because of the second half of the story when they were in America. Really bad American actors, and they kept changing the female lead's name. And the Chinese actors spoke in only Chinese, but everyone was able to understand one another? However, I'll definitely be watching the first half of this again sometime soon.
