Parents need to know that this has been one of the most aggressively marketed animated movies in recent history. Jerry Seinfeld has left no promotional stone unturned, so chances are that if you've had NBC on in the house for more than 20 minutes, your kids have seen a commercial for this movie. The good news is that it's a film that even preschoolers can follow, and while there are a few tense moments (mostly involving Barry's pell-mell flights through Manhattan), there are no overarching villains or monsters -- or even that many pop-culture references to frighten or confuse kids. There are still a few jokes that will go over little heads, but they're mostly about things like being "Beeish" (the insect equivalent of being Jewish), Larry King, and the boredom of working too hard. Oh, and a mosquito makes a blood-sucking lawyer joke.
