There seems to be no theory that can explain what happens in this movie that fits all the facts portrayed. It reminds me of the later episodes of "Twin Peaks" or "Lost" - the story starts to go off the rails, and you realize it has gone beyond anything the writer can do to justify the previously revealed facts.SPOILER ALERT: The first half of the movie shows two characters who have just met each other; halfway in, there is a scene where the characters pretend to be married, and then the second half of the movie shows the same two characters, but now they have been married for 15 years. It's interesting in a way, but you'll be disappointed if you expect it to come together in the end and make any sense.
