When I watched Jaws for the first time, it reminded me of one of my favorite books: The Old Man and the Sea by Ernest Hemingway. The appeal of Jaws is not the shark; we only even see the shark two or three times in the entire movie. The point of the movie is Martin's determination to protect his island and the psychological and physical struggles he will endure to do that; this is, in my opinion, very comparable to Santiago's struggle with the marlin. These two narratives are respectable and inspiring. And that, I think, is what makes Jaws an amazing movie (and it's sequels not so much).
