Good God, that site practically makes it sound like a porno!
I teach 7th and 8th graders -- 11-14 years old basically. As they were leaving today I told them "Happy Thanksgiving and go see Rent." There is nothing in the movie that overrides the overall messages of friendship and living life to its fullest. Unless your daughter is especially immature for a fourteen year old (and I'm guessing from the fact that she already knows the show that she isn't), she will be fine with what's in the film.
The movie got the same rating as Harry Potter -- will you let her see that?
Hi, Shirley Temple Pudding.
