Analyzing message in "Quentin Tarantino's comments on Film vs Digital"

In the following blog post I analyze the message in the video interview with Quentin Tarantino.

Out of all possible purposes that the author has listed on page 180, here are a few that I believe retain to my topic

Express an idea or opinion:

Quentin Tarantino clearly feels very strongly about the changing of the guard from film to digital, even calling it the "death of film". So he obviously expresses an opinion.

Persuades the audience of something:

Tarantino does his best to persuade young filmmakers not to give in to the digital era and how film is so much better and more natural than digital. So he does try to persuade his audience and those who follow him that the digital era is bad for film.

Analyze, syntheses or interpret:

Tarantino interprets this event more than he analyzes it, he says that it is the "Death of Film" that is his thoughts on the issue, his opinion and his analysis of how the film industry is changing.

Here are the points that I do not believe are relevant to the text:

Informs the reader about a topic that is often mis-understood:

Tarantino doesn't explain about the issue of film vs digital he just comments on it. For a casual movie goer they don't care about this issue and shouldn't, but for a filmmaker who understand this issue they will understand what he is saying.

Respond to a particular text or occasion:

This revolution isn't a single event or occasion. It is a change happening over time. So he isn't responding to a single event but a change happening quickly.
