There is most certainly an audience for the film “The Mortal Instruments: City of Bones,” fans of the six (planned) novels about demons, supernatural demon fighters, vampires, werewolves, witches and warlocks.
They'll thrill to all the endless litany of runes, talismans, history and “rules” of this world of shadow-hunters descended from an angel that showed up to help crusading knights a thousand years ago. They'll eagerly await the brief, throw-away visit to the “City of Bones” (a cemetery) of the title.
And if you love exposition and shapely, if bland, young actors in leather, skinny jeans, knee boots, Goth cocktail dresses and heavy eye makeup, this may be the movie for you.
Lily Collins is Clary, the birthday girl whose mother (Lena Headey of “300”) never told her about her heritage, why she keeps seeing signs and people with great hair stalking and stabbing demons in nightclubs and what not. Clary, dragging her unsuspecting admirer Simon (Robert Sheehan) along, finds out. She was born into this world. Simon? He's just a “muggle.” Sorry, “mundane,” a clueless human.
They learn all this from the warrior-explainer Jace (Jamie Campbell Bower), who drives a Triumph motorcycle, flirts with Clary and has the tedious job of explicating every single thing to them and to the audience.
Sometimes, vampires interfere. Sometimes, werewolves help. A magical cup, a “mortal instrument,” is sought by good guys and bad (Jonathan Rhys Meyers).
