This is a five-star anime classic film, and it is not "iffy for 17-year-olds". Are you serious, now? This was originally rated 12 in the UK! I won't say this film is without mature content though. Violence: Lots of explosions, gunfights, and yes, the infamous arm explosion everyone talks about; however, it is all moderate. The one scene I'd classify as "graphic violence" though is a quite gory scene in a hospital in which a doctor and guards are mangled to death through telekinesis. There is very visible gore during this scene, so I'd say "know your kid" when it comes to that scene, or perhaps fast forward. Sex: A girl is attacked by a gang; they tear her shirt, and her breasts are visible for a second or two. It's not erotic in any way or played for laughs. Language: It really depends on the dub. The Pioneer dub released in 2001 (and a bit easier to find) has a scene in the beginning in which a character yells "Aw, f***!", but the original Streamline dub does not contain any spoken F-bombs. Both dubs and the Japanese versions contain sprinklings of mild language such as "d**n", "hell", and "a**", as well as a scene in which someone has graffiti-ed "f*** you" in the background; it's a very blink-and-you-miss-it shot though. Drinking, Drugs, & Smoking: Some characters drink and smoke, but it's hardly worth mentioning.
