Anyway, here's my thesis:
Raiders of the Lost Ark is not an action-adventure movie about an archaeologist who plays by his own rules and saves the day. Instead, the film is an exploration of Marion Ravenwood's crippling drug addiction. An addiction that was born from her unhealthy relationship and continued association with Indiana Jones.
Is it true? Who cares. Can I prove it? Well, not proof in the sense of research or evidence -- proof only so far as crafting an internally consistent argument, relying solely upon the clues within the movie.
