"The reason decadent super-heroes can seem so, so wrong isn't because sex and horror are wrong; it's because super-heroes are really meant for kids. There aren't stories where Thomas the Tank Engine turns into a vampire. There aren't stories where the Snoopy is gang-raped. There aren't stories where the Cat in the Hat starts ripping people's arms off. Because, you know, that stuff is for kids, and, aesthetic atrocity aside, you don't want to fuck up the brand."
Actually, I don't see what the big deal is. It's not like crazy people are dressing up like overly-hyped superhero villains and stabbing babies.
