quiet thriller with great act from meryl streep and take a slightly different route with the paranoid performance from roy schnieder . unfortunately some other of the other performance be quite poor and with the standard dumbed down cop . slow to pick up and it worth stick with past the stock plot setup routine . there some neat camera work to strengthen the guessing game and make you feel the paranoia and fear of the doctor . there a fantastic sequence in central park where the doctor follow a mystery woman and lose her beneath the light \ dark pool of street light . use the sound of her footstep to pull your attention forward to a tunnel . the final moment of that sequence be brilliant . throughout the lighting be use to great effect with all other sens and even performance extremely restrain . a good film which i be sure have influence many others of this genre .
