There's a sex ed video explaining human reproduction. It's kinda making fun of what we watched in jr. High, with that same level of explicitness.

It's implied that couple has sex. A woman eavesdropping licks the doorframe of the room they are in,

There's implied woman attempting to rape a man.

No nudity. A guy is shirtless once. But nothing sexy. There's an implied girl-girl relationship, but we don't see them get affectionate with each other.

There's a lot of blood, intestines, giblets ... all of thjat.

Depaitated human head is used as food by monsters.

Heads get chopped off. It's bloody.

The word "fuck" was used once. Later someone says "freak" instead.

People turn into monsters and the monsters are nasty. There are scenes where monsters hunt people. A lot of screaming about who is going to be killed.
