Vigilante is a gritty, violent, and controversial revenge flick. Vigilante gets compared to Death Wish often, but vigilante is the more fulfilling and entertaining film. Robert Forster stars as a father and husband who gets driven to the point of vigilantism after his son is killed and his wife deformed. Forster performance is deep and fascinating. Director William Lustig (who also directed the trashy and gory Maniac) adds a sense of realism and desperation to the film and the violence seems very authentic. Fred Williamson is GREAT as the leader of the nieghborhood vigilante group. The son's death is quite disturbing and the ending is satisfying (unlike the death wish ending). You really hate the criminal scumbags and cheer on their demise. There are some great one-liners too. Vigilante is the ultimate revenge exploitation flick.
