There was an actual story in Superman Returns, which my family and I took in last night.
The story is about a young man named Clark Kent who went away to find himself, and came back home having failed in his quest. However upon his return he discovered that during the time he was trying to find what he did not have, he lost even what he had left behind.
The rest of the movie is about Clark's rediscovering his place in the world he had once thought to abandon in favor of a personal quest.
In a nice bit of irony Clark ends up getting the piece of "home" (Krypton) he had sought, only to find that it was deadly to him and to the home he knew. To save the home he knows, he has to get rid of the one he had spent years looking for.
That is a nice allegory for life really. We are meant to be with God. We were designed for that relationship, and yet we spend out time looking for it elsewhere. We end up finding that the life we are trying to find is poisonous to the one we really need.
I recommend Superman; he really is just an alienated person, looking for where he belongs. We belong with God.
