It's just something about these bad boys ;) If you have some that I haven't seen, please recommend!
Beautiful Mind, Lee Young Oh, the main lead is sociopathic because of external forces (he wasn't born that way). Drama was only 14 episodes, but very unique for a kdrama.
According to the dictionary an anti-hero is “a central character in a story who lacks conventional heroic qualities and attributes such as idealism, courage and morality.” But to me the lure and appeal is that they are redeemable. That though they are flawed, in the end they do the right thing and stand up for the one(s) they love.
My favorite “superhero” from comics was the anti-hero Wolverine. Bad guy turned reluctant good guy, always with a sarcastic quip ready, but deep down he fought for the downtrodden. I know he’s not from Dramaland, but he is the epitome to me of anti-hero because he wasn’t trying to be but yet always had honor and ended up reluctantly joining the good fight.
