When they work organically for the character, they're fantastic. When they feel shoehorned in, they suck. Like just about anything else. And that dichotomy of organic vs. shoehorned is why I don't really have any superhero ideas anymore. I did, but I realized that I was basically forcing myself to start from a certain standpoint, and that I didn't really have anything new to bring to superhero storytelling, any formal innovations. I had pretty unique superpowers, but that's not really a story. I started to feel like there really isn't anything left to say with the superhero. The fact that he is a superhero must now be incidental to larger stories. Astro City and Watchmen and the like have exhausted the few remaining possibilities for crafting an interesting, intellectual narrative around superheroes that can stand for a long time as an artistic accomplishment. All that's left now is shared-universe soap opera.
