Common Sense Note
Parents need to know that although this mature anime series is a fairly intelligent example of what science fiction is capable of, it's not for those who take their sci-fi lightly. It's extremely dense and complicated -- following the plot requires lots of effort -- which means it's likely to appeal most to teens and adults who are already deeply committed to the genre. Those who watch can expect frequent violence (including suicide bombings and terrorists) and some language.
Female characters have exaggerated curves and some revealing outfits -- as per normal in anime. The unedited Japanese version (which isn't what airs on U.S. TV) includes partial nudity.
Suicide bombers, terrorists, and more.
Some use of words like "hell" and "damn."
The series serves as an overall metaphor on the problems of relying too much on technology, as well as a treatise on the horrors of war.
There are video games and a movie related to the storyline/characters.
Drugs / Tobacco /
Some characters smoke and drink.
