It comes back to bite you in the ass!
Two of our leads return; Brody and his wife, and their fates intertwine with that of a new killer shark... or possibly the same one. They are still played by Roy Scheider and Lorraine Gary who manage to recreate their original chemistry. This said, the global vibe isn't exactly matched. Where Jaws was first and foremost a drama, Jaws 2 embraces horror and feels like a deliberate slasher.
The writing, here, isn't as keen. The new story is dangerously close to the original and it conveniently depicts a hero with no notoriety or credibility in regards to previous events. Aside our two leads, no actor in this shines through. The shark of Part 1 was sneaky, smart and resilient. The new one is meaner and more prolific. It is so proactive it feels supernaturally enhanced.
The fact that we have to deal with protagonists already broken and depressive when the film starts puts us in a dark mood from the get go. There’s a beach full of mindless partying tourists to lighten the mood, though, who are mostly there to graphically succumb to an aquatic rendition of horror villains such as Friday the 13th’s undead serial killer Jason Voorhees.
