Saw the movie, was very good. I'm a bit confused as to the deeper meaning of the ending quote (which is very nice):
Eventually, all things merge into one, and a river runs through it. The river was cut by the world's great flood and runs over rocks from the basement of time. On some of the rocks are timeless raindrops. Under the rocks are the words, and some of the words are theirs. I am haunted by waters.
