There is absolutely nothing to recommend this film at all. There is none of Paul W. S. Anderson's sometimes visual flair, no interesting characters (Mads Mikkelsen's Rochefort and James Corden's Planchet are possible exceptions), nothing exciting happens and the story is just two episodes of Dogtanian stuck together (with a shoehorned in Fistful of Dollars joke) with everybody speaking in their own accents. Even Christoph Waltz' performance is flat.
Real rubbish.
