Due to the film poster and the title & (unimaginative) subtitle, I thought I was going to see a superficial action film. Very wrong, from the beginning I noticed a film with good acting, also in many supporting roles (like Anweis) and even short roles (Cipolla), with a smooth pace (giving space for calm shots of silent reaction of actors), atmosphere, fantastic background music, original scenes, a script with some kind of unexpected twists, etc.
Ok, there are quite some cliches - some which work for me well, as making clear it is a detective story, film noir like, etc, and others which don't (the cartoonlike introduction of the assassin, the dumb detective caught of guard -?? -, the bad bad mafia leader). Anyway, the films gains in complexity and has really interesting (and some beautiful) scenes.
I enjoyed the film, and to be true, I think the former title should have been kept : Legacy. I finally understand at the end of the movie the actual title, and revealing it then is an interesting idea, but it leads to associate the film to other style of products (assisted by the ordinary poster and the empty subtitle).
