Hopefully the gang gets round to doing Jaws The Revenge as well, because that takes bad film-making to an unprecedented, operatic level of shit. The shark is after the Brodies. How does a shark know the Brody brother works for Amity Police, and that he's on duty that night and will come to clear the trap at the harbour? How does the shark know that the other Brody brother works in the Caribbean, and that the Mum is going to fly down there? The shark is *waiting for her* when she gets there - does it have access to airline passenger manifests? Can it use a computer?
I have a theory that in Jaws The Revenge the shark is in some kind of aquatic FBI and the Brody family are the antagonists. The first shark was unethically hunted by the Chief and his accomplice with the fishing boat. The second was investigating that murder and was electrocuted in a murderous cover up with the help of a complicit Amity community.
In Jaws 3, another shark is investigating this seagoing crime family, and stumbles on the rampant animal cruelty and exploitation at Sea World, and not only pays with her life trying to expose it but her child dies at well.
Jaws The Revenge is in fact a downbeat policier following a relentless shark FBI agent who won't rest until the Brodies pay for their crimes. He's crossing all sorts of lines because THIS TIME IT'S PERSONAL. His captain at the precinct says "That's it Jaws, you're too emotionally involved, I'm taking you off the case." "God dammit Cap, not when I'm this close!" "OK Jaws, you've got 24 hours, and if you're wrong it's your dorsal fin in the fire..." In the end there is no justice for the sharks because the humans are too powerful and ruthless. Forget it Jaws, it's Chinatown.
