This year is the half-century mark — the 50th anniversary of Steven Spielberg's original summer blockbuster: Jaws. You can hear the music, can't you? It changed the way we watch movies and the way movies were made. It was full of happy accidents and success out of necessity — and it was followed by three astonishingly bad sequels, establishing yet another firm American cinematic tradition. We're talking about our love for JAWS, and we're talking about those other ones, too.
