Jaws is a perfect movie poster in that it tells you everything you need to know about the movie in one simple sheet: a terrifying killer shark is gobbling up beach-goers. You can easily make that assumption from the poster, and when you saw the movie your expectations would be met and exceeded. But not all posters are like that. There are many, many, many posters that are vague and downright confusing, and if you didn’t know anything else about the movie other than what you saw on the poster you might expect something completely different than what the movie actually turns out to be.
