The following is a brief summary of the content found in this horror film that's been rated R. Profanity includes at least 43 "f" words, while other expletives and colorful phrases are also used. Some sexually related dialogue is present, while the bare breasts and bare butt of two of the humanoid type creatures are briefly seen.
Violence consists of the humanoid cave dweller monsters attacking, killing, and eating some of the humans, while some of the latter fight back and kill the creatures by various means. All of that has extremely bloody/gory results, and those scenes, various moments of peril, many jump scenes, and the claustrophobic nature of the film's setting may be unsettling, suspenseful, or downright scary to some viewers.
Some bad attitudes are present, including a woman not being a good friend to another woman (including talk that she had an affair with her husband). Other tense family material includes an introductory accident scene where a woman loses her husband and child. Some characters drink, while two briefly smoke pot.

For those prone to visually induced motion sickness, there's a bit of bouncy camera work during some aerial shots, while all of the quick edits, etc. in the caves might create that result in some sensitive viewers.
