The problem with this is that you often miss the stuff that the author was trying to say. Turns out stories have themes after all. For instance, you're factually wrong about Lord of the Flies. The pig wasn't the first thing they ate. The island is described at the very start as a natural paradise with more than enough food to feed all the boys. Jack starts hunting because he wants to kill, not because he needs to eat, and it unfolds into this whole primitive religion celebrating murder. It gets pretty explicit when the boys start killing each other while chanting ritualistic hunting chants. The ending very directly links the savagery which inexorably unfolded on the island to WWI when a bunch of British naval officers show up and say, "wow, can't believe nice civilized boys would do something like this," while staring at their battleship on the horizon. If you commit yourself to this weird attitude that subtext and metaphor don't exist and everything is literal, you miss out on the ideas underlying the text. That's exactly why high school English class tries to get you to dig deeper.
