Many comedies that include detailed or crude sexual material or drug references appear in this category, such as A Very Harold & Kumar 3D Christmas (2011), The Hangover Part II (2011), and Project X (2012).

Most horror movies that include gory violence and nudity are placed in this category, such as Drive Angry (2011), Piranha (2010), and Underworld: Awakening (2012).

Many adult dramas, with elements ranging from sexual themes to disturbing violence, also appear in this category. Consider The Kids Are All Right (2010), Love & Other Drugs (2010), The Girl With The Dragon Tattoo (2011), and Drive (2011).
