i think that was actually the point. just giving the small intro and the rest of the story unfolds in everyone's imagination.
"imagine" is the first word that appears, i think that, no matter what everyone says, this video was great cause it set the mood for the creation of a story, yet it did not control the story. we get to do it. it's like the author is saying: "it's your turn". I enjoyed it very much :D Too bad it was so short.
