Wrong side of the iceberg
I remember someone once explaining minimalism in literture to me by describing an ice berg. Most of the mass remains hidden, whille only the very top sticks out of the water. When it comes to story-telling, the ice berg model translates to a "show-don't-tell" mentality. Into the Wild did too much telling, concepts were overly explained with heady Thoreau quotes and title cards of the protaganist's journal entries. When the film works it manages to close the philosophy textbook and let the viewer contemplate the efficacy of removing oneself from society. Unfortunately, these reflective moments are nearly crowded out by tedious exposition and theorizing.
