The first two-thirds are brilliant. As for Olivia Wilde and her riveting performance:

[. . .] it’s still good to see a cunning and capable actress rise above her usual projects, such as stupid fodder like Tron or Cowboys and Aliens, or labels like “Sexiest Vegetarian Celebrity of 2010.”

After Enough and five Death Wish movies, the revenge genre is not without its recurring clichés, many of which get defrosted and microwaved again in A Vigilante. The point, if there is one, is that “heinous criminal felonies are acceptable if they are justified by a woman driven beyond the limits of reason.” As one battered wife says, “Every graveyard is full of people who didn’t make it.” The same is true of old movies gathering dust in Hollywood film vaults.
