Movie nightmare

My husband and I are fortunate to have my mother living just 45 minutes away from us. She adores her granddaughter and gratefully keeps K on occasion for us. She kept her a couple of weekends ago so that D could work, I could have a garage sale, and we could enjoy a "date night".

We decided to eat a wonderful dinner at a local Thai restaurant and then go to a movie. (Is there anything else to do on "date night?") We decided to see the comedy "Knocked Up" and looked forward to enjoying the comedy. Much to our dismay, sitting next to us was two adults with their two children (ages 4 and 6?). We were surprised to say the least, but weren't quite sure how the movie would go; based on the storyline knew it was inappropriate for children that age.

FIVE minutes into the movie, we were both shocked and appalled by the amount of nudity. We were both VERY uncomfortable having these children sitting down a few seats from us. Have others seen this movie? It is a funny story premise and the acting isn't terrible, but I can honestly say that it was the most graphic movie I have ever seen in regards to drug use, nudity, sexual content, and foul language. D and I spent the entire movie wondering if we should say something to the parents down the aisle, who clearly were NOT uncomfortable with what their kids were seeing. For those of you who haven't seen it, I'm not talking about a pot smoking scene, sexual inuendos, and an occasional curse word. The movie was OVER THE TOP with drug scenes, sex scenes, and every other word seemed like it was "f*&k".

The movie was uncomfortable enough, but the fact that these kids were watching in the same room just floored me. We could have gotten up and left, but frankly, we were kind of waiting to see what would happen with this family. I debated the entire time on what to say to the parents and how to say it. Even after it was over, as the family was in the game room with the kids, I contemplated saying something to them. Nothing mean or rude, but just let them know that it made ME uncomfortable that their children were present at such a movie.

I know people take kids to movies at different ages and of questionable content...but for those of you who have seen this movie, you understand what I mean when I say, it was VERY obvious within the first 5 minutes that this was no regular movie. It bordered on soft porn. I don't even know what it is rated (I pray "R"), but given the front row full of young teens, I'm not so sure.

My questions are these: Should I have said something to the parents? If so, what does one say in that situation? What parents let their young teens see such a movie? (I assume most people aren't aware of how graphic it was, since we certainly weren't aware) Finally, am I just old???? :)
