A female character walks around her apartment wearing only a shirt and underwear.

Some blood and intense sci-fi violence.

One "F***" muttered under the breath while a character is under intense stress and psychological pain.

One character is seen smoking a cigarette.

The screeching and wailing "Night Terror" creature may be frightening to children and even teens.

Overall, seems like a PG-13 movie for language and violence. Also note that there are subtle references to Masonry.
