Everyone is trying to sound so brilliant and goth. It's a slow boring movie about slow boring people who have lived too long without passion or "beating love". Adam and Eve never left the garden , and yet never bothered to explore it. They know so much, yet experienced so little, just living from one drop of blood to another, contaminated not by impurities, but by the meaninglessness of not being able to see enough. At the end Marlowe gets it. They all truly are dead.
They missed the whole point of life and love. No struggles, no strife, no suffering, just more blood. I don't know how they don't kill themselves from their own boredom. LIVING LONG DOESN'T MEAN LIVING WELL! Sometimes you just got to know when to give up the ghost.
