. . . from the company's point of view, at least!
I pay about $10 a month to rent a succession of movies. Not a bad deal: it's convenient, shipping is easy, there is wide selection of DVDs available.
The problem, from my point of view, is that the last disc shipped to me was City Of God, in late December 2006. Now, of course, I have been traveling around the world much of the time since then. But in the five weeks plus since I've been home for spring term, I have yet to watch this movie. So I am paying about $120 a year to rent 2-3 DVDs. They must love me at Netflix Central!
