A bewildering mixture of painfully familiar tropes and dishearteningly under-sketched characters gets the blender treatment in this latest big screen adaptation of young adult adventure fiction, based on a series of five novels by Cassandra Clare. Vampires, werewolves, warlocks, demons, portals to other dimensions and enough symbology to make even Dan Brown giggle all feature prominently in The Mortal Instruments: City of Bones, a sci-fi/fantasy quest of awakened destiny that starts out strongly but loses steam after a half-hour, cycling through a catalogue of tween-stamped CGI mayhem en route to a conclusion less thrilling than shrug-inducing.
