Parents need to know that mature themes (racial and cultural intolerance) are the central issues of this film. Frequently disturbing imagery and an odd sexual scenes make this one appropriate only for older kids. Kids will see alien creatures eat each other and human-like creatures get stomped on by much larger aliens and killed by alien contraptions. A humanoid casually kills an animal with a knife. Some scenes show large groups of people killed en masse. At one point, the planet's dominant race of Traggs adopts a policy of genocide against the subservient race of human-like Oms. Characters appear in various degrees of nudity. In the film's strangest moment, we see how the Tragg race mates. Their mental forms (depicted as bubbles with a Tragg inside) attach themselves to the necks of headless nude statues, which then proceed to dance with one another!

Families can talk about why the filmmaker chose to animate such a weighty film when people tend to associate cartoons with children's shows and humor. Can you think of other comics are cartoons that are for more mature audiences?
