The Grant Morrison run is really good (don't listen to GothamCity on this!
). It is Batman set in the DC Universe though, so if seeing him be more super-hero than Chris Nolan-vigilante isn't your thing, you might not want to check it out (don't worry, Batman is still badass).

I'm a big comic book guy. I read about 40 titles a month and started back in '99. Although I only really found stuff I enjoyed from '01 to now.
