I believe that people are drawn to fiction because it is an escape for then its a different reality that they can go to, to escape the real one like Harry Potter, Star Wars, and The Hobbit they are all fictional and people can use them to escape this reality to a better one in their mind.
Creon is the tragic character in the play “Antigone”. Creon's tragic flaw, hubris, causes his downfall. Creon will not listen to anyone. He is stubborn and his pride is so great, he can not bring himself to acknowledge that he could ever wrong.
If you have to write about this (never read this) but you could be broad with what you say. Use things such as the timeline of the story, the actions the characters do and the emotions they feel. Of these things are possible in real life then of course it's realistic.
