It has its funny parts, but is mostly lame. I was a little surprised that it was rated G. Too much naked humor, lots of scary stuff for very little kids, and there was very little humor. Two stars.
I have the DVD of this movie and I think it's really good. It has some mild violence/martial arts violence and sad moments that might be too much for the youngest kids, but nothing too bad for kids 5+ and it has positive messages about the importance of family and being brave. Violence: Some VERY mild martial arts violence during a dream. The babies (when controlling a large mechanical Reptar suit) battle with Jean-Claude (who's in a large mechanical snail suit), destorying some structures, but nobody gets hurt. Some sad moments, like when Chuckie is watching his friends dance with their moms to a sad song. But nothing too bad for kids 5 and older. Sex: Coco is shown engaging in mild flirting with Chas. Spike is shown forming a "relationship" with a French poodle and they share a romantic dinner (parodying the famous scene from "Lady And The Tramp") Angelica is shown stepping on Coco's dress, tearing it and revealing her underwear. But nothing graphic is shown or mentioned. Consumerism: Based off the popular TV show, "Rugrats" and one scene in the movie parodies the famous dinner scene from "Lady And The Tramp"
