Wow, I never noticed the two phones. I can't add much to the analysis. I love the father/son mimicry, the spare use of the shark (I didn't know of the mechanical issues until much later), the dolly zoom on Brody at the beach, the defaced billboard, the exuberance of the chase.
Even before I saw the theatrical release, I was as gripped by Jaws as the entire country. I adored the poster. I had Jaws Halloween costume when I was 7, I bought a book called Sharks: Attacks on Man in '75 from the Scholastic book fair.
I was 6 when Jaws was released. I was too young for my parents to take me (although my father took me to Papillon when I was 4, so WTF?) and as a result, had the movie a bit diluted before I managed a proper viewing. It had been a TV edited movie that I'd caught in fits and starts until it finally came back to the 99 cent revival theater. As a result, Close Encounters was the Spielberg film that left the biggest impression on me as a kid, while Alien (I can't believe it's not on the list!) was my 'Jaws'. Rated R, I somehow got my father to take me when I was 10. It took me quite a few viewings to actually watch the whole thing.
Jaws is an elemental, primal terror that I can never get enough of. I love almost everything about the movie, and I can forgive Hooper's survival, just for the relief it grants Brody after the ordeal. I needed it as much as he did, to know it was over.
