^ Yeah, I suspect that the idea is for you to make of it what you will.
But this is America, we are too stupid to realize that!
Honestly I enjoyed the film and so did a friend who I saw it with, we never disgust the ending because we probably see it differently. All I said to him about the movie is how this was supposed to be this insanely smart movie, that it was hard to follow, would go over everyones' heads. It wasn't any of that! People are just stupid! The movie explained everything they needed to point blank, in your face, and people after the movie finished went "I loved it, but I don't understand it!" Idiots.
Just take from the movie what you want to take from it and enjoy, it doesn't need to be over analyzed to death.
