Comic books are a pulp art form, like novels or film or anything else. If it's done well, it's done well, if not, then it blows. A lot of the great stuff, especially pertaining to Batman, is pretty dark and for a generally older audience.
Are comic books popular where you live, too?
Honestly, I'd have no idea. I find comic books difficult to read and accordingly have no interest in them. To me ... well, I think of all this Batman and Spiderman stuff as being on the same level as Thomas The Tank Engine or Road Runner or Bugs Bunny. After all, those cartoons were all played together on children's morning programming when I was little.
Though now I'd like to see somebody make a darker Thomas The Tank targeted at an older audience.
