There's some general positive messaging about perseverance, survival, and new beginnings in the face of an undead apocalypse, but it's far from the series' focus.

Grotesque zombies are frequently featured, many of which attack -- and are killed -- in a graphic manner. A mother is shot in front of her young daughter, and a young girl shoots a woman. Corpses are shown in the wreckage of a plane crash.

Minor reference to teens dating.

"Sucks," "ass," and "hell" are used. Characters "flip the bird."

The series is a part of the hugely popular The Walking Dead franchise, which sells everything from t-shirts and toys to comic books and video games.

Characters smoke and teenagers drink alcohol. A character illegally makes the latter, and gets drunk with another character. The illegal alcohol is referenced frequently and its creator is briefly imprisoned.
