At a Cleveland-area high school in the late '70s, senior John "Derf" Backderf (Alex Wolff) and his cronies decided to make a mascot out of the graduating class's oddest duck-the disruptive and death-fixated Jeffrey Dahmer (Ross Lynch). The insights into the depressed teen's sad home life with his combative parents (Anne Heche, Dallas Roberts), and the hints towards the path of a serial killer he'd soon follow, mark this adaptation of Derf's graphic novel memoir. Vincent Kartheiser also stars. 107 min. Widescreen; Soundtrack: English.
