Not to piss off Dylan Wang Fans but if you want to use your own voice in a costume drama, work on your accent + line delivery. Success of Love Between Fairy and Devil (which I did enjoy) was partially contributed by the right choice of voice dubbing (Sound, Accent, Line Delivery). Of course, I would love it if more actors can use their own voices but that's under the condition if they can do it properly. It's the same concept where European/Australian actors that play American characters with the correct accent. I am sure it's hard work but it's part of acting.

From acting, many of his expressions are the same--that wrinkle between the eyebrow Look. Not comparable to the strong supporting cast. So many good actors can deliver those micro expressions.

Story wise ... kind of makes no sense how fast he solves the 1st case in 3 min. Lots of talking w/o actually going through the process of solving the murder. If you enjoy well written murder solving dramas like Imperial Coroner or Ancient Detective, then this is not it.

What's "Watchable"
Supporting Cast. There are so many familiar faces that can do these dumb humor roles very well. Although this kind of humor may not hit for everyone. 80% didn't hit for me. I much enjoyed "Go East" with Tan Jian Ci or The Happy Seven in Chang'an. Both are silly comedies that hit more for me.

I'll emphasize that these are just my personal opinion. I am not a super fan of any idol actors, but I am a fan of character portrayal and good story telling disregarding popularity.
