Oh yes, I forgot. My mom pulled my sister and I out of The Life of David Gale and made a big production of stomping out of the theatre, complete with loud, disgusted mutters so that the people in the back row could hear.
I guess extramarital bare boobies and sexy thrusting in Shakespeare in Love were OK, but adulterous standing-doggie-style sexy thrusting from behind was not. It was a couple years later that I finally got to see the rest of the movie.
