".....Even the scene where Alex Kintner dies displays Spielberg's balance of seriousness and dark humor. The way he builds tension throughout this scene is almost playful and comical. Brody is on shore, intently watching the water, but he keeps getting interrupted by townspeople bothering him with petty troubles, to which he half-listens while craning his neck to look over the shoulders of the people he's talking to. Out on the water, Spielberg cuts between multiple swimmers: a woman floating on her back, a couple wrestling and kissing, a dog paddling after a stick thrown by its owner, a kid on a flotation device (the doomed Alex), other kids splashing and screaming, attracting Brody's nervous attention with each squeal or shout. The cutting is lively and playful, knowingly generating suspense that takes the form of a question: Who's going to die? Is it this person? This one? This one? Is the shark going to appear now? Now? Now? Spielberg seems to be having fun drawing out the moment, engaging in some Hitchcockian manipulation, delivering multiple false scares before finally getting to the real deal. The scene is very complex in its tonal blend, with black humor running through the slowly building suspense, before the scene climaxes with bloody horror and then gives way to the sad aftermath.
