Uncle Buck may look like a kids film, but it is really more along the lines of a teenager film. The movie contains heavy sexual themes, although no nudity is ever shown, several suggestive scenes and comments are like a woman dirty dancing with a man, a woman suspecting a man is having violent sex (even though he is just trying to use the washing machine) an overly horny boyfriend and a few more things that I don't need to mention. You get the point. That being said, the movie does contain a lot of language, but the language is PG 13 and not horrible. Not much to speak of for violence, any violence is not intense and most of the violence is probably meant to be comical. Uncle Buck does smoke in several scenes also. This all said, Uncle Buck is not a children's movie. No, it is not a bad movie, it is just not meant for kids. Let them learn about sex in school, not from you having to explain it in the most innocent way possible after they watch the movie and ask you about it.
