The Exterminator. 1980.
Another tough gritty film, Robert Ginty plays John Eastman a ex Vietnam Vet who goes about his ordinary life working and his friend is beaten and left paralysed. John takes it up upon himself to become a vigilante in New York.
This is more than just hunting the bad guys down and shooting them, although we don't see it but you can tell he plans things out by using fire or a meat grinder. Christopher George plays the no nonsense detective assigned to track down the vigilante and somehow manages to strike up a relationship with nurse Samantha Eggar. The film does have one strong gore scene which is a beheading at the start in the Vietnam sequence, certainly still enjoyable to return to every so often.
