On many occasions, I've written a post about the rather lackluster state of comics from the big two and invariably, the post will generate comments from people saying they've completely given up on comics "...ever since they cut off the Joker's face, or Avenger's Disassembled or DC 52, or..." you get the idea.
I totally sympathize with the frustration people might feel about the lack of quality coming from Marvel and DC (though the actual change in quality might not be as huge as you think it is, all things considered.) What I don't understand, is how this leads people to just give up completely on the genre itself.
People don't quite watching television shows because they didn't like how LOST ended. So why is it that so many people quit comics altogether because Doctor Octopus is now Superior Spider-Man?
I suspect the answer is that a large part of the readership isn't really that enthralled with the genre in of itself. That's why independent titles languish, but umpteen Batman titles reign supreme. It's not the genre that people like, but the idea that Batman and his universe is something they are partaking in.
The problem with that comes when writers do something with Batman that no longer fits with how you perceive his universe. Then you are left with nothing. Which is sad, because in many ways, we are currently in a new Golden Age of independent comics.
I would definitely encourage anyone who has "Given up on Comics!" to try some new independent comics. You might find yourself really enjoying the experience of discovery all over again!
