Common Sense Note
Parents need to know that The Originals follows a diverse group of vampires, werewolves, and witches living in modern-day New Orleans, adding a whole new dimension to the term "night life." Violent scenes can be sudden and bloody, and though sexual content isn't constant, you'll still see some steamy kissing and seduction and trace a major plot point stemming from a one-night stand. There's social drinking, too, although language is mostly mild ("damn" and "hell," for example).
Sexual content isn't constant but includes kissing and implied sex plus story lines revolving around sexual encounters.
Violent scenes can be pretty shocking, with throat-slitting, heart-ripping, and the obvious neck-biting. Blood flows freely.
Gateway terms like "hell" and "damn."
There's at least a sense that people from diverse worlds can come together to fight against something that's worth standing up to. That said, male characters seem to have most of the power.
Drugs / Tobacco /
Social drinking, both in bars and at parties.
