"Brief Reunion" adds a social-media angle to a time-tested thriller template, one that's been used to deliciously entertaining effect in such movies as "Strangers on a Train," "Purple Noon" and "With a Friend Like Harry": An old friend or new acquaintance insinuates himself into a seemingly tranquil life, with lethal consequences.
Writer-director John Daschbach's feature debut is efficiently told and features solid performances, but without the juicy character detail, vise-grip suspense or black comic intensity of its memorable forerunners, it unwinds as a boilerplate genre item.
The nightmare begins for New England entrepreneur Aaron (Joel de la Fuente) on his 40th birthday, when long-time-no-see college pal Teddy (Scott Shepherd) takes his online friend request to the next level.
Armed with an inappropriately expensive gift, he crashes the celebratory dinner that Aaron's wife, Dartmouth instructor Lea (Alexie Gilmore), has planned. The shifty Teddy accelerates his stalking, posting increasingly incriminating photos on Facebook until Aaron takes the blackmail bait.
