Because everyone has passionate opinions about love and sex, romantic comedies have always had to play it safe and try to please everybody. Audiences don't go to romantic comedies to be challenged, but rather to have their mores and misconceptions reinforced. That's why such films seem so strange years later -- romantic comedies from the 1960s look like something from Neptune -- and yet why conversely they're so interesting: Romantic comedies encapsulate an era's baseline attitudes about love and sexuality... Bottom line: To take the moral temperature of America, don't look at the risque films. Look at what's supposedly innocuous.
