The scope of stories superhero comics can give is extremely limited. Even the superhero stories I'm enjoying at the moment still are nothing ground-breaking, they haven't been for a long time. I read Image's and Vertigo's titles and the scope of stories they tell is astounding. One issue I'm in a sci-fi western, then to an uber-ficitonalised version of the Manhattan Projects and then a deep, inter-galactic universe with NEW characters that I am constantly unravelling and becoming attached to.
Superheros got me into comics but independents kept me around.
