It astonishes me that no one watching the dialies during production on Jaws: the Revenge caught that they were making one of the worst sequels in cinematic history.

I'd have figured their first clue would come when it came time for the underwater shark sequences. Based on what I processed through my visual cortex during this film, I'd say the way they got the obviously paper mache' / plastic shark to move was to have a diver float next to it off screen and push it so it would glide past the camera. Seriously, the shark in this film demonstrates about as much movement during the underwater sequences as a fucking Lincoln Log.

There's also some silliness about the shark seeking revenge on the Brody clan and a completely ludicrous finale to round this crapisode off. This includes the funniest moment in shark movie history, when the Great White (apparently having developed vocal chords with which to let fly bellows of icthyological rage) leaps from the water and hovers just long enough to be rammed by the bow of a yacht. What makes this scene so funny is that at this moment the film cuts to what is clearly the classic shot of the exploded shark sinking beneath the waves from the original Jaws. Believe me, this was not the best time to evoke memories of the good movie.

In summation: the filmamkers decided to write an inane script, had a woman who appears to be 70 years old as the action hero/protagonist, tossed in Michael Caine and the kid from The Last Starfighter as part of an apparent attempt to kill whatever career either one might have left (Caine recovered, but the ploy seems to have worked for Lance Guest) , didn't try to make the shark convincing and then didn't even bother to film a new shark death sequence.
Now THAT'S cheese.

One of out of ten excellent attacks on a banana boat which are the single reedeming moment of this film.
