I have repeated this complaint so many times it will surely start sounding like a rant by now. About half-way through the excellent movie The Dark Knight, Commissioner Jim Gordon abandons the Joker to Batman for questioning.
Batman’s first act is to slam the villain’s head on the table, really hard. Then he hits him on the hand; the Joker’s hand was lying flat on the table. Question: how is that necessary or even remotely useful to the story?
The Moral Angle
The Joker went through a lot of trouble joker slot to try and kill Dent. He is an awful man. He is a psychopath, a very real menace to the entire city of Gotham. He hurts people willy-nilly.
The police and Batman have an urgent need of the information the Joker is withholding. Harvey Dent and Rachel Dawes are missing. Harvey is an important figure in Gotham City, not only because he is the D.A., but especially because he represents hope and a peaceful future for people in the city. As Jim Gordon puts it later, he and Batman “bet it all on him.”
But still, at the time of the interrogation, the Joker is a prisoner in police custody. That makes hitting him unnecessary abuse of power. That makes it torture. That makes it ugly and useless. Batman is so much stronger physically not to mentioned armored, trained, supposedly a role model.
In 2008, when this movie comes out, we should be aware of that. I sometimes zap away to check what else is on when watching this scene on TV, to come back a few seconds later for the good parts. I have probably seen it 40-50 times so far.
On the narrative side of the issue, the screenwriters could have used a different path for the story. They even have enough material to borrow from; over 50 years’ worth of comics and graphic novels, some extremely good.
