“A Vigilante” (*1/2 out of four) was a grindingly unpleasant and tedious death-wish pulp thriller about a former abuse victim (Olivia Wilde) who takes it upon herself to help victims seek refuge and retribution against their assailants but soon finds that both her past and the law are catching up to her. Potentially juicy revenge thriller is undone by molasses pacing and meaningless and artless directorial touches that can’t decide whether to make this a shoot-em-up or a dramatic statement about violence and relationships. Wilde is terrific as usual but this muddled clunker is a poor showcase for her. Second half- source of the film’s title- is particularly tough to endure.
