This urban crime drama is a diverting entry with plenty of action, tense moments and running dialogue to sustain interest for the duration of the film. The main plot is a hostage situation and a demand for an outrageous sum of money. Denzel Washington and John Travolta spar throughout the picture and play off each other very well. Denzel, as always, is great and Travolta makes a good heavy although some of his one-liners fall flat as he negotiates with Washington. There are several interesting scenes of the trains, subway stations, tunnels, track beds and elevated sequences where the action takes place. Some of the street-level scenes, involving taxi and police car stunts don't seem to be necessary. Cast and camera work are very nice.
