I do a lot of work and research on DC, more than I do with Marvel. And I'm a Marvel guy through and through, but I like DC a lot, because I feel like DC has a lot of great concepts with their characters, but they're not doing them right.
For instance, Wonder Woman. Who is Wonder Woman? DC tries to make her one of their "Big Three", but that character has rarely been written well, or been popular in terms of comic stories. Is she a warrior? Is she an ambassador? Is she a teacher? Every writer comes along and tries to write her differently, and none of them seem to stick.
And Superman. Superman is a great character that nobody knows how to write. And they're doing this thing where they try to make him relevant and interesting, but they approach it the wrong way. They think Superman killing people is somehow the kick they needed (so much so that he committed three murders in 2013; General Zod in *Man of Steel*, The Joker in *Injustice*, and Doctor Light in *Action Comics*).
If you really want to make Superman interesting, it's simple. What do you do with a character that always does the right thing? Put him in situations where there is no clear right thing. Put him in extraordinarily grey situations, with no clear good outcome and no clear good decision. We all have those moments in our lives, and that's the connection and humanity you need to have Superman feel vulnerable.
I have a whole mini-podcast thing done with Meso about DC that I should upload someday. It goes into more detail. Some day...
