Roy Scheider again gives a good performance as the police chief in this more-of-the-same first sequel that's a couple of notches down from the original. Once more the citizens, again led by Murray Hamilton as the Mayor, won't believe him about the shark menace and even go as far as firing him. There are as many teasing shots of swimmers taken from below the surface as the plot will decently allow before Scheider and the shark come to their final showdown.
