Technically, "Amsterdamned" is about as good as any average American thriller about serial killers and tough cops; Dick Maas directs competently, shows a sense of humor and the unusual setting is an extra plus (how often do you get to see a boat chase in the Amsterdam canals? Not even the Bond pictures exploited that opportunity). It's just that the whole concept of the film treads on all-too-familiar territory, and that there are a few too many climaxes, making the film feel protracted. (**1/2)
