What parents need to know
Parents need to know that The Mortal Instruments: City of Bones is based on Cassandra Clare's best-selling urban fantasy series about warriors, demons, vampires, and werewolves and is the first film in a proposed action-fantasy franchise. Expect a lot of violent confrontations in the movie -- mostly using special blades and swords -- including scenes of torture and even death. Language is mild ("damn," "what the hell," etc.), and romance is limited to longing looks, a big kiss, and some sexy outfits. Like the book it's based on, the movie features a diverse cast and a brave female protagonist.
