Common Sense Note
Parents need to know that the movie begins with typical tensions, resentments, and competitions between two brothers, aged six and 10. Their father is divorced and their teenaged sister is distracted by her interest in boys and parties. The film includes scary music, scary sound effects (crashes, explosions, alien-monster growls), and some images of space-aliens and a big robot attacking the boys that might be frightening for younger viewers. Boys use some obnoxious language ("d--k," "screwed") and violence against the aliens to save themselves.
Teenaged sister wears a tight top in preparation for her night out; she develops a crush on a character who turns out to be her younger brother at a later age.
Space ships are armed with guns and futuristic missiles, lizardish space aliens are menacing; crazed robot attacks boys; meteors and space weapons blow up the boys' house/space ship.
Minor language, including kids' use of "d---k," "screwed," "ass," and "bee-yatch."
