Schoenbrun, however, was also also making a very frank media study about the way our favorite teen TV shows came to inform — or perhaps misinform — our most formative years. Schoenbrun's new film, "Teenage Sex and Death at Camp Miasma," is also a profound and emotional work of media analysis, this time targeting the corny, sexist, transphobic slasher movies that Gen-X grew up watching in the 1980s. All of those things, in fact, are namechecked (sometimes with an eyeroll) in "Sex and Death." "Sex and Death," then, becomes a '20s essay on the sexual realities that rest within the genesis of all slashers. It loops back around and rediscovers the cathartic sex and death that sparked all this mess to begin with.
