Epic poetry is probably one of the most ancient genres in existence if not the single most ancient genre, but nobody really composes epics any more. It would be tough to write an epic poem in the modern world without a sense of irony (which would almost certainly ruin the epic) because we've become very skeptical toward heroes. This in itself is kind of odd, because we also expect a lot more of our heroes than our ancient ancestors did. They only expected their heroes to be fantastically competent and fantastically brave. We expect ours to also be perfectly moral, which is beyond their reach. If we find out one of our heroes has a moral failing, we rip him to pieces for it.
