Film censor defends Batman rating :

The BBFC has justified giving The Dark Knight a 12A certificate after getting more than 80 complaints about the Batman film's disturbing content.
The film regulator's spokeswoman Sue Clark said the sequel was a fantasy movie with only implied violence.
But she admitted that the British Board of Film Classification had carefully considered giving it a 15 rating.
The 12A rating states that a film should not "dwell on violence" and "does not emphasise injury or blood".
The film contains a scene in which The Joker, played by the late Heath Ledger, is beaten repeatedly by Batman in a police cell.
