Although the movie's overall message -- that you should always be careful (not "even on vacation" but "especially on vacation") -- could be seen as positive, it's couched in gore and sadistic violence.
Positive Role Models & Representations
Some grisly thriller violence, including graphic stabbings and shootings, plus fistfights, bloody wounds, and extreme moments like the mutilation of murder victims (shown on-screen), where teeth are removed and fingertips cut off to obscure a victim's identity. A character is shot point-blank but survives; viewers see the wound after the fact. An animal is hunted, eviscerated, skinned, and cooked. A victim is stabbed in the leg and pulls the knife out. A man, struck with a knife, has his hand split badly between his fingers (the wound is shown in detail).
Nude male and female buttocks shown during a skinny dipping scene. Shielded female toplessness. Discussions of sex, including the offer of "a B.J."
Fairly strong language throughout, including "f--k," "motherf--ker," "s--t," "hell," "ass," "Jesus," "Christ," "crap," "craptastic," "oh my God," "goddamn," and more.
Brands visible or mentioned by name include Trojan, Hummer, and Marvel Comics.
Ease of Play
Chracters drink hard liquor and smoke marijuana. A psychotic killer is clearly fueled by crystal meth use.
