His sociopathic, horror film–loving older brother, Steve (Ethan Philbeck), keeps a rotating collection of severed heads, primarily taken from black women, in a bowling-ball bag. When he tells Steve the name of his most recent bully, Marty can't see the consequences (though the viewer can). Philbeck is the best-in-show here, chewing the scenery and clearly having a blast as a fledgling then full-blown madman. (And as the final few scenes show, he's either blessedly endowed or rocks a prosthetic penis with Mark Wahlberg's Boogie Nights éclat.) Writer-director Scott Schirmer eschews the ironic approach, thankfully, and instead works to pull genuine tension from his material. He does that quite well, and any unintentional laughs (or eye rolls) are icing.
