Paranoid people with guns are a menace to society

A tad outdated I'd say. The film was released in 1992 and it depicts the 2008 London after an ecocatastrophe. Detectives Harley Stone (Rutger Hauer) and Dick Durkin (Alastair Duncan) are hunting down a serial killer out of this world. I liked this and its contemporaries back in the day just fine, but merely a warm memory now.
