Should be fine. I can't recall any obscenities (hard to remember when you aren't specifically listening for them) - even if there is, it's nothing worse than what is said at school (mostly sh*t, hell, that type of thing), and nudity is limited to brief side breast shots of the alien women (its the type of clothing they run around in), and maybe butt cheeks since they wear small loincloth/thong thingies. There is only one "sex" scene between aliens but it's pretty mild. Obviously, there is violence and some blood. Not too sure if the plot will hold a 6 year olds attention, especially since it is over 2 1/2 hour movie.
