Query: Juvenile and Vulgar

I was severely disheartened to see my current favorite actress, Catherine Keener, involved in such a juvenile, vulgar and surprisingly unfunny movie. To her credit, it was mostly tolerable when she was on screen. I can only hope that she was not aware of how badly improvised this movie would be and accepted based on some other factor.This may appeal to 15-year-old virgins since they may find the quality of humor directly proportional to the amount of expletives used. I was merely annoyed and bored.
