Swearing within the first 30 minutes--inappropriat - Ice Age: The Meltdown Reviews

I was unhappy with the movie. We expected a family movie--based on the commercials. However, it was a pg-13 movie unfortunately with swearing within the first 30 minutes of the movies--more than once--and not even necessary. Both children (2 and 4)fell asleep, and we left early. I have never reviewed a movie before, but I felt the way this film was marketed to young children was inconsistent with the adult humor and swearing.
