This series presents an unrealistic portrayal of teenagers, but it deals with the very real issues that teens face. Themes also include disparities between socioeconomic classes. The consequences of negative behaviors are sometimes not always discussed (or shown).
Some of the plotlines feature characters surviving violent crime, including physical abuse, shooting, and rape. A character is murdered in a later season.
Frequent scenes of teens kissing and "making out." Frequent references to sexual activity. Discussions about teen pregnancy and sex are also featured, including discussions about virginity (particularly Donna's) and unexpected pregnancy (Andrea's). The episode in which Dylan and Brenda had sex for the first time was a big deal when it first aired.
Pretty mild: "Damn," "hell," "bitch," etc.
Many (but not all) of the characters are presented as wealthy, materialistic members of the upscale Beverly Hills community.
Drinking, Drugs & Smoking
Teen cigarette use (accompanied by a clear discussion of their consequences). Alcohol and drug abuse (including steroids) are shown to have clear negative consequences. But the underage characters still do plenty of drinking outside the context of abuse.
