I believe an anti-hero is someone who does not follow the law and is usually seen as a bad person, but their intentions and actions are good. My example of an anti-hero would have to be Batman. Bruce Wayne is a very wealthy  philanthropist who's parents were killed when they were being robbed, and ever since then has wanted revenge. He makes Batman up to take the law into his own hands and fight crime. This is what makes other people see him as the anti-hero. All that Batman does is for the good of everyone and his intentions are good, but he never follows the law. In society we see the hero as someone who follows the law, someone to look up to, and someone who will always be there for you to protect you. Batman fits perfectly with the movie mainly because he is someone who breaks the law but does it for the right reasons. He may be seen as an anti-hero, he may go against the law and do what he feels is right or necessary at the time which may be illegal, but Batman does it all to try and protect the innocent.
