Al Pacino isn't particularly searing in this urban heroin drama, a precursor to much better films like Trainspotting, which really pushed the genre. But credit must be given, I suppose, to pioneers like Needle Park, which has Pacino and Susan Dey-lookalike Kitty Winn dazed and frequently comatose through nearly two hours of drugging, culminating in an inevitable bust. More a character study than any kind of narrative story, it's moderately worthwhile but far from a classic.
