Oh I thought you meant they would recount the events to him and it would be shown through flashbacks. I'd rather begin with Krypton. Everybody knows that he is rocketed from a planet that explodes. It's as iconic as the Waynes deaths. But if they were to keep a large amount of history blank, to sound more idealised, which is torn down by Zod and Brainiac though. But I have to say, I do hope they get the scene from Secret Origin where Clark sees images of his parents, Martha feels insecure next to his goddess of a mother and Jonathon feels insignificant as his father was a brilliant mind of a society, Clark runs out, and Jonathon comforts him and reassures him he is still his son. And to me if they can get the Birthright message to his parents make a very powerful message it is everything he explores throughout the film that makes him Superman.
