(Spoiler Alert: If you haven't watched the movie Logan and are planning to, you may want to read this essay only after you do.)
In generic heroic sagas, the hero leaves home to face numerous tribulations in a pilgrimage of the self.
The obstacles along the way are tests of the hero's strength, molding his/her character through pain and suffering. Glory, when achieved, is bittersweet, as it comes heavy with loss, usually of loved ones, family or companions. In tragic sagas, the hero pays with his/her life in the end so that others may be free.
