Short answer - (12A) rated film content

"Have Hollywood attitudes towards content in 12A films become more liberal or have audiences’ film desires changed?"

The core substance of this question is philosophically investigative in the sense that there is a reciprocal cause and effect between the two co-variables of content sensitivity and the audience's desires. It may be argued that Hollywood attitudes have become a lot more liberal today than traditionally before as previously taboo topics within categories of sex, gender, ethnicity and disability are a lot more openly portrayed and available for discussion in modern narratives of films. This can correlate with institutions adopting the idea of raising awareness for audiences and the much speculated craving for controversy which has been proposed by theatrical critics. Therefore, to some extent it could be rightfully concluded that Hollywood attitudes are directly reflective of the audience's desires, possibly so because of the increased influence of users on the producers of the media.
