Aside from a waste of a couple of hours the most recent (loosely recent, it was 5 years ago) installment of the superman franchise offers this quote from Superman's (Kal-El's) father, Jor-El
"Live as one of them, Kal-El, to discover where your strength and your power are needed. Always hold in your heart the pride of your special heritage. They can be a great people, Kal-El, they wish to be. They only lack the light to show the way. For this reason above all, their capacity for good, I have sent them you... my only son."
At first glance it's a rather cliche voiceover to introduce the concept of a comic book/sci-fi film, but if you look closer you may see something that seems familiar: "I have sent them you... my only son". Could it be that this film is an allegory for Christianity?
To put it bluntly....No!
What it does appear to be though (IMHO) is a rather apt allegory for how people view themselves, and may think this is how they would be described by some far off alien being.
"They can be a great people Kal-El, they wish to be. They only lack the light to show the way" Mankind can be great, we can live up to our potential, and be good. All we lack is someone to go before us and show us how it's done. Give us a role model, someone that will show us how we should act, behave and live and we'll be that great people. We have the capacity to do good, we just sort of need a few hints to get us started and we'll be away.
Sadly, this just doesn't match up with our experience in the real world. We have all followed the example of the first man, Adam, and have the capacity for failure, sin and evil. We are fundamentally bad and no amount of effort, wanting to be good or guiding lights can change the state of our hearts. All have turned away, they have together become worthless; there is no-one who does good, not even one (Romans 3:12).
What we need is a quote of "You see, at just the right time, when we were still powerless, Christ died for the ungodly"... "For this reason above all, I have sent them you... my only son".
