Orgasm and nuclear holocaust are the controlling factors in this horny, delirious fantasy by the talented Gregg Araki (Mysterious Skin). The hero (Thomas Dekker) is a hip college freshman longing for gay sex but also open to the physical ministrations of a British party girl (Juno Temple); meanwhile, his best pal (Haley Bennett) has gotten into a hot-and-heavy lesbian romance with a fellow student (Roxane Mesquida) who turns out to be a witch. Araki captures the fever of bisexual exploration with his hot color palette and nubile actors, but at the same time he spins a bizarre sci-fi intrigue—complete with cryptic messages and fearsome nightmare sequences—that recalls Richard Kelly’s teen cult masterpiece Donnie Darko (2001). Funny, scary, and exuberant, Kaboom delivers the goods as both a generational marker and a tale of things to, uh, come. 86 min.
