The terror is in what you can't see until it's too late...

I've always believe that. I hear a lot of "show, don't tell" from so-called movie "experts" but let's be honest: If you can hear it and even smell it but not know what "it" is (under the right conditions) you can create some serious terror in a movie through characters and the way they respond to that thing they can't see....until it's too late.
Jaws is the very embodiment of that idea.
You combine that music with just the right elements and then, just at the last second, that giant mouth comes out of the water.
I didn't go near the open water for months as a kid and walking across docks, at night, freaked me out. I could "hear" things but i couldn't see what was making the noise.
Half of Jaws is the building up to it and then they have to deal with the shark. They've seen it but it still goes under until the final confrontation.
"Smile you son!", a gunshot, and boom, that sucker gets blown to Hades.
