When writers don't know what to do with a character, they build up the supporting cast and universe to kind of hide that fact. After a while, you can no longer see the character for the underbrush. When that happens, you need to bring out the weed-whacker to clear some of that away so you can focus on the main character.
There was a point when comics were considered to be mainly of interest to kids, and it was decided that kids could relate more to someone their own age than an adult. So suddenly all these previously grownup comics were lousy with sidekicks: Aquagirl, Aqualad, Robin, Kid Flash, Speedy, Stripesy... the list goes on.
A story is a story is a story. The only difference is in the techniques you bring to bear. There are always limitations on what you can and can't do. But I enjoy that. Just like when you write a sonnet or haiku, there are rules you have to abide by. And to me, playing within the rules is the fun part. It keeps the brain fresh.
For me, growing up in a ridiculously poor family living in dead-end neighborhoods, Superman was a deeply personal icon, one that said you can do anything if you put your mind to it. What he stood for formed the core of who I wanted to be as I grew up, and informed how I view the world and my responsibilities to other people.
I also like to look at the dynamic that takes place between religion and science because, in a way, both are asking the same questions: Who are we? Where do we come from? Why are we here? Where are we going? The methodologies are diametrically opposed, but their motivation is the same; the wellspring is the same in both cases.
We know that if memory is destroyed in one part of the brain, it can be sometimes re-created on a different part of the brain. And once we can unravel that amino chain of chemicals that is responsible for memory, I see no reason why we can't unlock it and, essentially, wipe out what's there.
