Some surgery is done on male characters, and you can see their bare chests and backs. Surgery is not graphic at all.

Some romances and relationships. A few kisses.

A few dead bodies are seen throughout

Many animals, such as wolves and sabretooth tigers attack people, some blood from injuries is shown after.

Some blood seem throughout, but the show is more frightening than grisly

Several dead bodies found. A dead, decomposing man. A few men with veins popping out inflamed. A man with his arm torn off. None have been too gorey as of early s1, but can be frightening.

None to speak of.

Mild language.

Some alcohol and marijuana use

A stash of heroin is seen

Overall dark theme that may be disturbing to some viewers

Opening scene is unexpected and very frightening

A massive sinkhole opens and engulfs a number of people, buildings, and cars

A man contemplates suicide and puts a gun to his head

People are attacked by animals etc.
