One important thing DC has that I love is a classic sense of mythology. Their characters are larger than life and represent human qualities that readers aspire to and feel inspired by. Superman, Batman, and Wonder Woman are cultural icons for a reason. The Flash and Green Lantern rest on the concept of legacy, history, relationships, and their powers lend themselves to expansive stories about space and time travel. I could go on. Each character on their own just brings so much to the table. Each character is like a universe onto themselves. What matters just as much if not more than the powers or the fictional backstory is the person underneath. DC characters may seem simple because of their prevalence in pop culture but they aren't. They are complex and different approaches in their writing tap into different themes in humanity. They feel like very real people, but they are also important symbols. DC has plenty of room for grit, flaws, tortured characters, and street level heroes too. But it offers so much more, and when it comes to heroism, character development, and powerful literary themes, DC takes it.
