Ben begins the movie defiant of his parents' rules and eager to set his own course, but events open his eyes to the importance of being part of a family.
No cursing, but you'll hear "butt" in the dialogue (as in "kick your butt"), and Ben and Gwen call each other names like "doofus," "dweeb," "nimrod," "pea brain," and "stupid."
Ben 10 is a popular character among grade-school boys, and the character has been revamped for several TV shows and movies. There's also an extensive product line that bears the character's name, including video games, action figures, toys, and clothing.
