rhetorical question based on the reading assignment

After reading the article "What is digital Cinema?" by Lev Manovich, the question I came up with was - "This article is kind of like selling the idea of money as a way to revamp the barter system, isn't it?" There is hardly a shred of this very short article that everyone doesn't know already. Obviously people realize that filmaking has changed, one point not stated in the article is that large studio films have become exponentially worse (Transformers) and more like lengthy advertisements (Transformers) as they have increased their use of digital post-production. Maybe a better question would be "why was this article written?" I think Manovich may have written the article because he has stock in Industrial Light and Magic and is a big fan of Tom Hanks.
I think it would have been a better article if: A. He had concentrated on the cost effectiveness of digital media as a tool to achieve an end that looks finished as well as B. Digital cinema's ability to be conceptually maleable- more so than a way to galvanize your studio's profit machine.
Isn't it cool how movies are made? Making film is so easy, even a caveman can do it.
