Subtleties of Jaws, "I think we're gonna need a bigger boat"

Rating: 8/10 (13 February 2017)

First, I'd like to start by saying that I know everyone has seen Jaws so why write a review? Well I haven't seen anyone talk about the subtleties that are present in Jaws that complete the film.
The first use of subtlety is the shark itself. It is almost never seen until the end, which makes it scarier, not being able to fully comprehend what it is, although fully comprehending what is going on. The use of POV shots linked with the classic score clues you in on what is going to happen next without showing you the shark. The beach scene feels like chaos to Chief Brody, who is in charge of taking care of the shark. It feels like he has no control over what is taking place.
A bit foreshadow I also happened to notice at around 24 minutes, I think, Brody is flipping through a book. In one of the pages there is a picture of a shark with a tank (like the one at the end) in it's mouth. Obviously foreshadowing how he'll take out the shark at the end of the film. I didn't notice it until really watching closely.
An under-appreciated aspect of Jaws is Brody's character arc. In the beginning of the film he is a bit of a pushover. The mayor doesn't really listen to him and he lacks confidence. He is also afraid to go into the water. As he journeys into the ocean on the hunt for the shark he starts to muster up his courage. After he finally defeats the shark, he is in the ocean, the only shot of him in water, and he is unaffected by it.
Lastly, I noticed that Spielberg will do a lot of shots that last about 1 1/2 minutes, that can show development of character or a scene. For example, On the ferry, the mayor and Brody are having a conversation about whether to close the beach and the whole thing is done in the one take on the ferry. During the conversation, every time the mayor tells Brody to keep the beach open, he moves closer to the camera. It emphasizes the mayor's greed of money earned from it and Brody's lack of confidence.
