Gregg Araki is back home again. After forays into serious drama with his career-best work in Mysterious Skin, then stoner comedy in Smiley Face, Kaboom finds Araki in the territory occupied by his defining mid-’90s “Teenage Apocalypse Trilogy“. Namely, teens, sex, violence, more sex, and finally, more sex. Oh! And an apocalypse! Where those previous films were more tonally apocalyptic, this one is more literal about it.
