The movie has some interesting ideas -- mainly about prey becoming predator and about women empowering themselves -- but it's so brutal that these messages aren't likely to be the primary thing that viewers take away from the movie. Plus, another message is that of revenge and killing to solve problems.
Very strong, primal violence against women (and men), with lots of blood and several dead bodies. Women are punched, dragged, tied up, and then stalked through the woods. There's an attempted rape scene, which is stopped when the would-be rapist is bashed in the head with a rock. Characters are shot in the head, stabbed with knives and sharp sticks, and throats are slashed. There's even biting, with great streams of blood.
Two female characters strip off their clothes after swimming in freezing water. They're fully naked onscreen for several minutes, though they're shown huddled together, covering up certain body parts, as well as in the darkness of the woods. But naked breasts and behinds can clearly be seen. A female character also flirts very heavily with a male one, and there's some general sex talk.
Almost constant use of "f--k," in nearly every context and in virtually every sentence spoken. Other words include "c--t," "p---y," "a--hole," "bitch," "ass," "oh my God," "Jesus Christ," "douchebag," and "blow job."
Drinking, Drugs & Smoking
Characters drink whisky while camping on an island and are shown overindulging, drinking with the intention to get drunk. But all drinking ends and is no longer an issue after the first 30 minutes.
