Fans of the television series will be happily at home with this movie, which takes its toddler heroes through two terrifying adventures — getting lost in the woods and having to share parents with a new baby. The children around me at the theater laughed joyously at the potty humor and only a couple of them seemed concerned by the drooling wolf, mischevious monkeys, or the other perils the children face as they try to find their way back home. Their parents smiled at a couple of sly jokes, the use of voice talents like David Spade, Busta Rhymes, and Whoopi Goldberg, and that failsafe bolster of flagging parental attention, baby boomer-friendly music. The Rugrats’ trademark “kid-cam” use of floor- level perspective provides a few bright moments, and the kids’ efforts to understand the world around them are occasionally fresh and funny. The movie is not much more than a long version of the television show, but for many in its targeted audience, that is just fine. Parents may use Tommy’s concerns about his new baby brother Dylan to talk about children’s fears of displacement and how Tommy, though frustrated, cares for his brother when they are lost. They should also be sensitive to any signs that children are scared when the babies are separated from their parents, though most will be very reassured by the way the Rugrats cooperate and (usually) support each other.
