Most inferior sequel of them all, with plot rehearsal of the original in a first half and slasher flick in a second, with faceless teenagers; even for your "Friday the 13th" standards. Being boring with the biggest body count in the entire franchise speaks for itself while mechanical shark never looked as fake and plastic as in this second entry. Why is it considered as the best sequel of the series is beyond me.
Best scene: woman puts herself on fire while being attacked by huge rubber-shark. Then the boat explodes! It's awesome. Its also nice to see Roy Scheider back as Brody, but the shark-food posing as a group of teenagers are all pretty awful. Its not all bad. But kind of.
