What Parents Need to Know
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.
- Families can talk about the relationship between the two brothers: how do they learn to appreciate and take care of one another? How do Lisa or their father fit into or affect the brothers' relationship? How does the absent mother (never seen on screen, though she arrives to pick them up in a car) figure into the family tensions?
