Common Sense Note
Parents need to know that this is a cartoon anthology, not to be confused with the Batman movie The Dark Knight. It's also unlike the various Batman children's TV cartoons over the years. The approach goes for a more "grown-up" Batman viewership/reader demographic, mainly via bloody PG-13 type violence, and not much humor. No Robin or Batgirl, and Gotham City is depicted as overwhelmed with gangs and bizarre evildoers.
Sexual
Content
A few bikinis and low-cut dresses briefly seen.
Violence
Blood gushes from Batman's wounds and in a gory hospital sequence. Decapitation and Bat-violence in a fantasy. Much fighting, gunshots, and explosions. One character shot through the head.
Language
"Ass" uttered once.
Social
Behavior
Batman never kills (except in an exaggerated anecdote we see dramatized) and seems to act noble and suitably heroic -- even though one story segment questions Bruce Wayne's motivations and crime-fighting roots in personal vengeance. The animated cast is racially integrated (though mostly male), and one segment concerns Hindu culture and mysticism, in sketchy fashion.
Consumerism
Tie-in to vast quantities of related merchandise.
