Batman isn't crazy and DC Comics commits "story genocide"
As part of WonderCon, they put on the Comics Arts Conference, which means smart people offering fancy opinions about comic books. It's kind of great. I had the chance to see a few of these sessions, including "Batman vs. Iron Man: Can Biology Best Technology?" (Answer: Probably not), "What's the Matter with Batman?" (Nothing diagnosable, apparently) and "Story Genocide, Fanboy Tears: The Moral Questions of DC Comics' 'New 52' Project" (Yup, genocide!).
To elaborate a bit more on some of this, the Batman versus Iron Man looked at what circumstances each could win a fight in, and while Iron Man generally had the edge, Batman's intelligence, planning and sheer drive left him with some hope. As for what's wrong with him, they ran down potential disorders he could have from depression to post-traumatic stress disorder, and ultimately concluded that the character has experience trauma but doesn't suffer from any of these disorders. As a fan of this stuff, it's nice to see it being treated seriously (or, as seriously as it's possible to take it).
