There are no wrong answers, only your opinions 🙂
Personally, I think an anti-hero is a bad guy that does good things. He might cheat on his wife, steal, gamble, etc, but when it “matters,” he ends up on the side of what’s good.
Han Solo is an example that comes to mind.
Han Solo is a reluctant hero. Not an anti-hero.
Hud (1963) is an anti-hero. He defies traditional morality. He’s almost heroic-ish in the way he defies others, and is willing to do things his own way. But the film is constantly showing other people, who have strong values, and how Hud often does the opposite. Despite being a horrible person, he’s not really ‘the villain’ either.
