(In theaters, December 2011) It goes without saying that sequels often aim to replicate the elements that made the success of their predecessor, and add something more. In this light, this follow-up to 2009’s Sherlock Holmes is an unqualified success, and maybe even a more enjoyable film than its predecessor. Front and center, of course, is Robert Downey Jr.’s fast-witted take on the title character, complete with instant-strategy monologues and slashy repartee with Jude Law’s dependable Watson. More importantly, though, Game of Shadows ups the ante by providing an antagonist that is strong enough to present a challenge to Holmes: Jared Harris’ Moriarty lives up to its literary namesake, and makes for a formidable opponent. It all leads to a climactic chess game that plays off a few of the series’ signature motifs. (Literary fans will see Reichenbach Falls appear and nod at where the film is going.) Casting Stephen Fry as Mycroft is a bit of a coup, while it’s nice to see Noomi Rapace’s high cheekbones get a bit of Hollywood gloss after her role as “The Girl” of the Millennium trilogy. Director Guy Richie once again provides an action-adventure take on the basic premise, along with light steampunk esthetics and slow-motion action sequences. (A blue-tinted run through a forest provides a quasi-impressionistic sequence of almost-still images.) While the end result doesn’t transcend the Hollywood holiday blockbuster genre, it’s a well-executed example of the form, keenly aware of its audience’s demands and almost eager to satisfy them.
