This is not a great film, in fact it can't even be considered a "good film," when you take into account the poor, confusing editing, ugly cinematography and some bad acting. What makes "The Exterminator" a valuable movie, is it's "grindhouse credibility. This is one of the few movies of it's kind that actually makes me a little sick when I watch it, and similar films like "Death Wish" and "Vigilante" don't succeed in doing that. Yes, they are both way superior films, but they don't pack the punch that this sleazy movie from 1980 achieves in spades. You have the Vietnam Vet, still feeling the effects of one jungle, when he is thrust into another jungle, the urban jungle of New York city at the very end of the 1970's. The film's anti-hero is hunting the true filth of the Earth, mafioso, child molesters and murdering gang members. At the heart of the story is an ongoing struggle between him and "The Ghetto Ghouls," a hyper violent gang that is terrorizing New York. Offering some great, vintage location scenes of New York landmarks, like the West Side's meat packing district, the crime ridden Central Park, and the slime ridden Times Square. For these qualities the movie has value. It's a rough movie, but this one should be appreciated by fans of violent revenge movies from back in the day. The version I saw on Bluray appeared kind of choppy, like some scenes were missing. If there is an even nastier version of this one in existence, I can't even imagine what they cut..
