John Sayles scripted this Jaws-onland rip-off, with Robert Forster as the cop chasing a giant man-eating monster down in the sewers. Forster's dogged, and some of the set pieces are pretty nifty, but the plot's farcical, and this isn't strong on intellectual content despite its obligatory eco-message. The sequel is a made-for-TV retread, of practically zero interest.
