A thick, rich slab of American cheese, this high-spirited sex comedy by the Broken Lizard crew (Super Troopers) blends the Troma Films formula (gore, bare breasts, scattershot satire) with some of the niceties of mainstream filmmaking (acting, editing, a script). Swingers congregate on a tropical island resort presided over by washed-up 70s pop star Coconut Pete (Bill Paxton); drinking and humping abound, but the young staffers are being stalked by a serial killer. As bad-taste comedies go, this is more clever than gross: in one scene a dying man asks his lover for a last kiss and then, as she's about to oblige, specifies that he wants to watch her kiss another woman. Jay Chandrasekhar directed. R, 103 min.
