From plot to transition, from angle of lens to rhythmic montage, from editing to tone, from contrast to freeze frame..., you can get the impression involving Guy Ritchie, who may be referred as the Godfather of Film Noir. This story starts with a priceless emerald, a squad of slack guards and two gangs of thieves, one of which is amateur, while the other is professional judging from the looking. It is not difficult to speculate what would happen from this kind of stereotyped beginning. We can't tell which part is the imitation and which is the original. It's a concise and smart comedy, somehow, whose genre is quite different from traditional dramas we can watch at the Chinese cinema. Anyway, for the director, we can say, it's almost an perfect homework. It would make somebody laugh, but it is difficult to have the audience impressed as a milestone movie.
