Common Sense Note
Parents need to know that this made-for-TV Disney movie is heavy on social mishaps. Characters are frequently (and needlessly) bullied, though many of the victims are rescued by the heroes, who go back in time to prevent the incidents. Some of the bullies antagonize their victims simply because they like being mean, and some characters see their social status climb because they choose not to defend friends who find themselves on the wrong side of the jock-geek divide. That said, the movie's message is to show how people can transcend that kind of stereotypical labeling.
No sex or nudity, though there's some kissing. One couple argues over infidelity issues.
Some slapstick antics and frequent bullying, but no fighting.
No swearing, but frequent name calling -- particularly "geek," "nerd" and "dork."
Plenty of stereotyping of high school characters, including jocks, geeks, and cheerleaders -- though the point of the movie is to show how people can transcend these labels. The heroes steal a key scientific formula from NASA to build their time machine and later must lie to teachers to hide the device. A popular guy cheats on his girlfriend but gets what he deserves when she breaks up with him. Lots of bullying, often just for the sake of being mean (but the heroes try to prevent these incidents).
