The fact that it is so gratuitous is what makes it great. A lesser director would have allowed the studios to cut it, because it doesn't "move the story forward" or other such BS. Instead he gets to tell us what he thinks of the Winkelvosses and their tiny world, in a way I've never seen before.
the opening credit score where Mark is running through Harvard was beautifully crafted. totally set the tone for the 1st half of the movie. Great electronic composition with sparse organic elements.
