Listen to Spielberg or Scorsese talk about movies. They know and can quote from hundreds. And I don't mean quote as in "recite lines from," I mean quote as in "explain how each movie works." Movies are intricately made emotion machines. They are Swiss watches of precise gears and spinning wheels that make them tick. You have to be able to take them apart and put them back together again. In the dark. In your sleep. And your knowledge of a few movies you like is not enough. It is also not enough to know all the movies of the past five years. You have to go back, see the lineage of many types of movies, know what movie begat what in the line of succession, and how the art was advanced by each.
