> a director watching a cut of a movie, weighs every detail with a focus that is quite unlike the mental state of the public audience. I think that changes the way they watch all films, always dissecting.

Viewers do this as well. Analysis of literature and of television/film overlap to some degree, and both require an active consumer of the material.

I think the question is: Given an equal amount of effort on the part of the consumer, does one medium convey more benefits than the other?
