Admit it right damn now: Jaws is kind of a dumb movie. Sure, it's the best shark-based film of all time, but only in the same way The Texas Chainsaw Massacre is the best chainsaw-based film of all time -- it's a completely ridiculous idea that someone happened to get right once. People have tried to recreate that magic time and again since then to no avail.
The reason for this is simple. Just as it is with a chainsaw, there are a very limited number of ways to kill a person using a shark. They aren't viable horror movie villains. The chances of them invading Manhattan or joining forces with a fellow predator without it looking like the most absurd shit ever are right on par with Leatherface recklessly waving his power tools around in any other part of Texas without immediately getting shot in the face by eight different Second Amendment enthusiasts at once.
Except in Austin, probably.
If you need further proof, consider some of the more "memorable" shark movies from recent history and what their respective plots entailed. One of them, Open Water, was literally just two unlikable dipshits floating around in the ocean waiting to be eaten by a bunch of invisible sharks.
The lead actors in Cast Away did way more entertaining stuff, and one of them was a goddamn volleyball.
The other, Sharknado, is the aforementioned "most absurd shit ever" that always results from crossing a shark with anything else on film.
