FOOTLOOSE is a nostalgia joyride that takes the form of a 80s quasi-musical. It's a ton of fun to watch, especially with friends. I admit, some of it is just good to laugh at, but a lot of it is genuine entertainment that has you smiling and tapping your feet.
The whole plot of the movie is about teenage rebellion against authoritative figures, so if you think your kids will be inspired negatively by that, for sure don't let them watch. However, for mature pre-teens and teenagers, this movie is a lot of fun. There is some questionable content. Teenagers smoke (both cigarettes and weed), drink, and do dangerous stunts with their cars without any apparent consequences. The drugs are a big problem in the movie. Although a teen with marijuana is portrayed as a negative role model, the main protagonists of the film drink and smoke, and are praised for being rebels when they do so. Make sure your kids are mature enough to know that this is wrong. In addition to that, there is some brief non-sexual nudity (naked guys are seen in a locker room from the back and side), and some talk is made of how the pastor's daughter is promiscuous (she is seen putting boots back on after sex with her boyfriend). The same girl tells her father that she's not a virgin, and he uses words like "fornication" to describe sexual behavior. There is some suggestive dancing, but nothing major. There is constant teenage language like "s**t" and "d**n", but it's nothing that your kids aren't exposed to in school. A teenage girl is beaten up by her boyfriend (we see her with a black eye and cuts on her face), and two boys play chicken with tractors.
