“Unhinged” (** out of four) was an unwieldy action thriller about a woman (Caren Pistorius) who induces the road rage of a psycho (Russell Crowe) who she honks her horn at and he will stop at absolutely nothing to enact revenge and turn her life upside down. Alternately tense, harrowing, unpleasant, and routine as film derives elements from “Duel” and also “The Call” among many others; not bad but film is overall too slight and too derivative to make much of an impact. Pistorius is solid in the lead but Crowe surprisingly isn’t and is atypically awkward and unconvincing.
