“Friday Night Sext Scandal” (** out of four) was a predictable teen melodrama about a high-schooler (Anthony Timpano) who becomes embroiled in a scandal exposing photographs of students at school which snowballs into a firestorm of arrests and near-tragedy. Timpano is winning and charismatic in the lead but film covers all-too-familiar territory and never has the compelling fire that it needs. The subject of “sexting” and online social-media drama is only superficially covered here.
