Limitless (Unrated Extended Cut + Digital Copy) [Blu-ray] (2011) for $13.49

Depending on your take-away of the visual inventiveness and jam-packed plot that drives Limitless to peaks and valleys of preposterous fun, drugs are either a terrible scourge or the fundamental solution to all of life's problems. Limitless isn't exactly a morality tale, but the made-up drug that turns Eddie Morra (Bradley Cooper) from a scuzzy loser into a master of the universe does become a metaphor for ambition, menace, devastation, and ultimate success.
