My 11-year-old son and I turned this off halfway through. The movie starts with Earth being destroyed, and the aliens are so scary he was afraid of nightmares. The aliens were drawn with great cgi, and their other-worldly voices were cool (with subtitles). But we saw enough.
The thing I liked about this movie growing up was that it was animated but it had great action. There are space ship battles, shootouts and fist fights. There are definitely several intense action scenes but in the end it is still PG. Some kids will love it where some more sensitive kids will be scared. The other thing besides violence is one scene where the main character is being medically examined and his towel falls off (we see his butt) and a scene where we see a female character's silhouette as she takes a shower.
This was my first introduction to the world of sci-fi when I was a kid. I enjoyed the creativity of the settings, aliens and story.
In the end, it's a good action movie for kids. Actually, it's good for anyone; I'm 21 and I still love it.
I watched this movie last night, and the last time I saw it before that was way back in 1998.
As for sexuality, you actually see Cale's butt for a second (making this the ONLY PG movie I know with nudity) and there's another scene where Cale goes into Akima's room and she only has a towel on.
For Violence, I think this is also the most violent PG movie I know, and there are actually a few scenes with a fair amount of blood in them. It's all gun fights and a few explosions though, nothing close combat.
Language: nothing worse than "D**n" and I don't even think that was in there.
Everything else: there was no product placement or drugs, and I guess you could say the Social Behavior leans towards a pause, because...

Korso backstabs them, but then sacrifices himself so that they can survive.
