Point of View
The Goonies ain't big on fancy tricks when it comes to how this story is told. There are no flashbacks, no flashforwards, and no flashsideways. We watch the Goonies' story unfold linearly, although it does jump back and forth between the kids and the Fratellis (and then Sloth and Chunk) for a bit.
But other than that, the emphasis is on the story itself and not on getting overly experimental with the telling. Leave the fancypants narratives to the Quentin Tarantinos of the world.
