Common Sense Note
Parents need to know that this is a more mature Batman cartoon than the ones they might remember from their Saturday morning-TV childhoods. There is real death (including a parent), much violence -- even if it's animated -- involving explosions, guns, knives, etc. There's even some unsettling imagery involving corpses and the Joker that may upset the youngest kids. Anyone unfamiliar with the Batman saga might have some trouble following the story.
Just a hint that Bruce Wayne and Andrea have spent the night together.
Much fighting, gunshots, and explosions. Some blood and dead bodies shown.
Batman never kills and seems to act noble and suitably heroic. Though his quest for justice suggests that being a vigilante has ruined Bruce Wayne's personal life, his righteous motivations and crimefighting are contrasted with the much bleaker personal vengeance mission of the Phantasm. Andrea is a particularly strong female character. Gangsters are of stereotypically Italian-American descent, and Gotham City businessmen, police, and government officials are mob-connected or threatening.
