Wow, I can't believe CSM is rating this as a 12...I think we must be talking about a different film. The language in this movie is absolutely atrocious. Based on the 12 rating my wife and I took our 13½ year old daughter on 6/9/12. Within the first few minutes the swearing started, and didn’t stop. At around 20 minutes, I leaned over to our daughter and told her that we were going to leave, to which she said “good”. I felt horrible that we had taken her to the film and exposed her to so much vulgarity. I highly suggest that CSM raise the age rating on this film to no less than 14.
We were at the AMC South Bay Galleria 16 (Redondo Beach, CA), and when we left the theatre, we spoke to Kevin at their customer service desk to let him know that we were very unhappy with the language in the film. He was very friendly, apologized and offered us a refund, or admittance to another film. We decided to see the Avengers, (rated 13 by CSM), and although there was a huge amount of action, I don’t remember hearing any swearing. The three of us loved the Avengers.
