Common Sense Note
Parents need to know that Star Trek: The Next Generation is pretty different from the original series. While the first series broke ground for addressing important social issues, The Next Generation is more focused on pure entertainment than social commentary. It's plenty of fun; the special effects are a vast improvement over the original; and many episodes do try to make a larger point, but in general the goal is simply storytelling. And that's just fine. The show contains frequent sci-fi violence, but for the most part it's bloodless. Swearing is infrequent, as is romance.
Sexual
Content
Mild flirting and occasional romance, but no onscreen sex or nudity.
Violence
Plenty of spaceship battles, phaser shootouts, and even the occasional fistfight -- but the conflicts are generally pretty bloodless.
Language
Infrequent use of verbal put-downs and swear words like "damn" and "ass."
Social
Behavior
The series highlights the importance of respecting other (alien) races and cultural traditions while co-existing peacefully. Storylines sometimes act as metaphors for contemporary social issues, like discrimination and ethical practices in scientific research.
Consumerism
Though no product references, Star Trek is a major franchise associated with many products.
Drugs / Tobacco /
Alcohol
Some social drinking, but nobody ever seems drunk.
