As a fan of Detective Dee movies, Zhou Yi Wei did not work for me. Thinking back to some of the Detective Dee actors:
Andy Lau
Yiheng Du (Who worked as Andy Lau's body double prior so Andy 2nd)
Mark Chao
The ideal image of Detective Dee is far from Zhou Yi Wei's. Not that he isn't a great actor, after all he was so good in Rebel Princess & Longest Day in Chang An.

It started out as a promising series with quality production and many familiar actors. Set, costume, lighting, makeup, all so good & the fight scenes were the best! Less (special effects) is more when you can see continuous sequence (if you like classic kung fu). Ep 24 where he fought 1:1 against the female was one of my favorite scenes.

The promising series quickly got killed by the storyline after 4 episodes. It was hard to stay engaged after the Empress was no longer part of the subsequent cases. I've watched it through for the fight scenes, but the cases were blah.....

Also, Zhang Ruo Yun listed as "Main" was not even a main actor. He was only a part of one case, and I don't even understand why the character was written that way. Totally didn't make sense to me, completely anticlimactic.
