The other night, I watched a rerun of the original Superman film from 1978. In it I noticed a considerable amount of time was spent showing how Superman ended up on planet earth. We saw his parents on Krypton, the escalating doom affecting that planet, and why his parents took the decision to place him in a pod and send him to earth. We saw his father Jor-El rationalise this to his wife, explaining how the differing gravities, and less advanced life forms of Earth would give their boy a positive advantage.
What did all this serve to do?
It rationalised Superman’s superhero powers. He would be able to fly because he was from a planet with a different gravity, he would be superfast & superstrong because his molecular structure was different, etc.
Basically it gave a reason why.
However far fetched the reasons were, undoubtedly they serve to make the film more believable. They explain why Superman has superhuman powers. And so do many other Superhero films – The Hulk, Spiderman etc, all explain away the superhero’s powers, adding an increased degree of believability that would otherwise be absent.
All this shows that if you...
