While Pixar's "A Bug's Life" is a film about insects aimed at children, Dreamworks Animations's debut film "Antz" is very similar but aimed at the more sophisticated older audience.
A troubled ant named Z is a worker ant who dosen't like to work. His friend who is a soldier ant decide to switch places. Z is then dragged into a brutal war with termites (which is an awesome scene), and gets stranded with the Princess of the ant colony. While trying to get back home, they run into hilarious mischeif and fall in love in the process. Sounds like a good plot but the film is very smart that little children won't get very much out of it. Not to mention, this film has some pretty surprising language for PG-Rated animated flick.
It's not one of the best animation films out there but its worth watching.
"You the ant!"
