The film's attempts at positive messages ring hollow. The supposedly virtuous main character turns out not to be. On the (small) plus side, a gay character who comes out isn't rejected.
Plenty of horror-movie violence, though actual moments of penetration/bloodletting are limited. Young people die: one with neck broken on a pool table, one stabbed in the brain with a pen. Also shootings, stabbings, and a person set on fire. One character allows her hand to be hit with a hammer. Another falls from a roof onto a mattress and is OK. Recollections of rape/molestation/attempted improprieties between an adult man and a young girl. Evidence of a person having cut out her tongue years ago.
Non-graphic references to sex, lots of hooking up. In one cut-short sex scene, a woman's bare back is shown from the waist up, but there's no graphic nudity.
Occasional use of words including "f--k," "s--t," "a--hole," "d--k," "hell," "crap," "oh my God," as well as innuendo.
Quite a lot of drinking by college-age young people, including spring break sequences and partying. One young woman seems to be a budding alcoholic. No consequences for the drinking. One med student forges prescriptions to sell to other students. Cigarette smoking.
