Bad fiction has to constantly remind you about the plot, because you've already forgotten why we're going there or why we're interested in that. Even the artist has to lay it out as he's going, because he isn't sure how to make it fill out until he's written it down during the course of what's happening.
When you become reliant on guideposts, you're not able to stand on your own. Your memory goes and you're forced to take cues from the narrator to remember who is good, who is bad, and what the reasonable solutions are.
The world can work however we want it to. Defy them with memory.
