Nerds are systematic thinkers, which means, for entertainment, we want to exercise our systemic comprehension muscles. We want to stare at a thing and figure out what rules define it. In the case of Lost, Abrams get this. He sprinkles hints of systems within the system of the show. He tinkers with time and with personalities to paint brief glimpses of clues. And then he changes everything because he knows that if we ever feel we’ve figured it out, we’ll bail.
