This movie is one part Robert Downy Jr's Sherlock Holmes, one part Wuxia silliness and one part Lupin which makes it a hell of a lot of fun.

The story moves along at a good pace and if you like detective stories you'll have fun with this. The film looks stunning with a wonderful mix of Art-deco and European with just a touch of pre war Shanghai. Prague is a wonderful stand in for the Golden city and is shot to look it's best with many old buildings and their interior giving a hint of elegance and class. The acting is top notch with Geng Han turning in a great performance as the titular detective with a great supporting cast.

I recommend giving this one a try its worth the effort.
